Sauna Blanket and Battery-Heated Apparel Burn Injuries

A Lifepro sauna blanket, a pair of 32 Degrees heated socks, or Velazzio heated gloves can reach a temperature that takes skin off. If a defective heated product burned you, you may have a Florida products-liability claim, and the clock is already running.

If a heated product burned you in Florida, you likely have four years to file a products-liability claim under section 95.11(3)(d), Florida Statutes, measured from the date of injury. If someone died, the wrongful-death clock is shorter, two years under section 95.11(5)(e). The defective product is the antagonist here: a lithium battery pack or heating coil that overheats against skin and causes full-thickness burns. Recent recalls and warnings cover the Lifepro Bioremedy infrared sauna blanket, 32 Degrees heated socks, Velazzio Thermo1 heated gloves, Fieldsheer heated socks, and several heated insoles. Do not return or discard the product or its battery, even if the manufacturer or Amazon asks you to. The product is the evidence. Photograph the burns and the device, keep the box and the Amazon order, get the burns documented by a doctor, and call. The phone rings to Graham W. Syfert, Esq., Of Counsel to the Soud Law Firm. There is no charge to discuss whether you have a case.

The Bottom Line: A Burn From a Defective Heated Product Is a Products-Liability Case

Here is the prayer for relief first. If a heated product burned you in Florida, you can sue the manufacturer and the seller for the defect that caused it. Florida gives you four years for a products-liability personal-injury claim under section 95.11(3)(d), Florida Statutes. If a defective heated device killed a family member, the wrongful-death deadline is two years under section 95.11(5)(e). Those deadlines run, and they do not wait for you to feel ready.

These products are marketed as wellness and comfort. An infrared sauna blanket promises detox and relaxation. Heated socks and gloves promise warm feet on a ski lift or warm hands on a job site. The promise is benign. The failure is not. A lithium battery pack or a heating coil sits in direct contact with skin, and when the temperature regulation fails, the device keeps heating. Skin in sustained contact with a surface near 156 degrees Fahrenheit can suffer a full-thickness burn within seconds. People who fall asleep in these products wake to second- and third-degree burns that need debridement and skin grafts.

You do not have to prove the manufacturer was careless. Florida adopted strict products liability in West v. Caterpillar Tractor Co., 336 So. 2d 80 (Fla. 1976), which embraced section 402A of the Restatement (Second) of Torts. You have to prove the product was defective when it left the manufacturer's hands and that the defect caused your injury. That is a different and often easier burden than ordinary negligence.

How a Heated Product Burns You

The injury mechanism is simple and it repeats across brands. A rechargeable lithium-ion battery or a resistive heating element generates heat by design. A safe product limits that heat with a temperature sensor, a feedback controller, and an automatic shutoff. A defective product omits or fails those controls, so the device keeps climbing past a safe surface temperature while pressed against the body.

Two patterns dominate. The first is the slow overheat: the device runs hotter than it should over minutes, often while the user is seated or asleep, and produces a contact burn that the user does not feel until the skin is already destroyed. The Simone Vilaire glove case fits this pattern, where a glove on its lowest setting overheated over roughly two hours while she slept. The second is the thermal-runaway event: a lithium-ion cell fails internally, vents, and ignites, sometimes even when the device is switched off, producing flame burns and house fires. The iHeat and Ocoopa incidents fit this pattern.

Burn medicine makes these cases serious. A full-thickness burn destroys the nerve endings, so the deepest burns can be the least painful at first, which is why sleeping users keep sleeping. Treatment runs to excision, grafting, scar contracture release, and sometimes amputation. Those facts drive both liability and damages.

The Products and Brands Burning People

The micro-niche is broad and growing. Below are the specific products with documented recalls, federal warnings, or filed lawsuits as of May 2026. Each is verified against a primary or contemporaneous source. Lead with the sauna blankets, because they are the high-dollar wellness products in affluent households, and they are climate-agnostic, sold year-round in Florida and Georgia alike.

Lifepro Bioremedy Infrared Sauna Blankets

On October 23, 2025, Lifepro Fitness of Howell, New Jersey recalled its Bioremedy infrared sauna blankets because they can overheat during use and burn the user. The recall followed 65 reports of the blankets overheating, including 32 reports of burn injuries.

The affected model numbers include LP-BRMDYL-BLK, LP-BRMDYL-GRY, LP-BRMDYR-BLK, LP-BRMDYR-GRY, LP-BRMDYR-BLU, LP-BRMDYR-PNK, and LP-BRMDYR-PRPL. The blankets sold from September 2022 through June 2025 for roughly $179 to $199, through Lifepro, Amazon, Walmart, QVC, and Dick's Sporting Goods. If you own one, stop using it and preserve it. Do not send it back before you have spoken to a lawyer about your burn.

HigherDose and Other Sauna Blanket Brands

HigherDose is a widely sold premium infrared sauna blanket brand, and the category also includes Velazzio and other imported brands. Burns from any infrared sauna blanket follow the same defect theory as the recalled Lifepro units: a heating element or controller that allows an unsafe surface temperature against the body. If a sauna blanket of any brand burned you, the absence of a public recall does not defeat your claim. A recall is helpful evidence, not a prerequisite.

32 Degrees Heated Socks Sold at Costco

On April 23, 2026, David Peyser Sportswear, doing business as 32 Degrees, recalled about 207,806 pairs of heated socks under CPSC recall number 26-435. The socks can burn the wearer during high-intensity activity that combines heat, friction, moisture, and pressure. There were 14 reported incidents, 13 of which were first- or second-degree burns.

The socks sold at Costco stores and Costco.com from August 2025 through March 2026 for $30 to $46. They are identified by the words "32 degrees HEAT" on the battery-pack casing, the battery packaging, the user manual, and the outer packaging. Owners can return them to Costco for a refund, but keep yours if it burned you.

Velazzio Thermo1 Battery-Heated Gloves

On July 31, 2025, the Consumer Product Safety Commission warned consumers to stop using Velazzio Thermo1 battery-heated gloves because they can overheat or develop hotspots and burn the wearer. The CPSC reported 137 overheating incidents, including 119 burn injuries. About 58,700 pairs sold on Amazon from September 2019 onward for $9 to $140.

The manufacturer, Jining Liexing Outdoor Products Co., Ltd. of China, did not agree to an acceptable recall, so the CPSC issued a unilateral warning instead. That is common with these import-only products: the overseas maker goes silent, which makes the U.S. seller a critical defendant.

Fieldsheer Heated Socks

In 2025, Fieldsheer Apparel Technologies recalled three heated-sock models, MWMS07, MWWS07, and MWMS05, after 11 reports of pain and discomfort that produced 4 burns and blisters during high-intensity activity. The socks sold from August 2021 through June 2025 for $80 to $130 at retailers including Scheels, Fred Meyer, Home Depot, Meijer, and Amazon.

iHeat and Other Battery-Heated Insoles

Heated insoles are the most dangerous corner of this niche, because the lithium-ion cell can ignite even when the insole is switched off. The CPSC warned in 2025 that iHeat heated insoles, made by Zhangfengqing of China and sold on Amazon from November 2022 through July 2024 for $48 to $80, caused 11 fires, explosions, or thermal incidents, including 8 burn injuries, some second- and third-degree. The CPSC has issued similar warnings about other imported insole brands. Dispose of a defective lithium-ion device through hazardous-waste channels, not the trash, but preserve yours as evidence if it injured you.

The Legal Theories: Manufacturing Defect, Design Defect, and Failure to Warn

Florida products-liability law gives you three theories, and a strong case often pleads all three. They are not redundant; each targets a different failure by the maker.

Manufacturing Defect

A manufacturing defect means this particular unit came off the line wrong, different from its own design. A pinched heating wire, a miswired thermostat, or a defective battery cell that vents are manufacturing defects. The proof usually lives inside the device, which is why preserving the exact unit that burned you is everything.

Design Defect

A design defect means the whole product line is unreasonably dangerous as designed, even when built to spec. A heated glove or sauna blanket designed for direct skin contact, but with no temperature sensor, no feedback control, and no automatic shutoff, is the classic example. That is precisely the design failure alleged in the Vilaire glove lawsuit. Florida evaluates design defect under the consumer-expectation and risk-utility frameworks that trace back to West v. Caterpillar.

Failure to Warn

A failure-to-warn claim says the maker knew of a danger and did not adequately warn the user. The strongest failure-to-warn cases show prior knowledge. In the Vilaire matter, the complaint alleges years of Amazon reviews describing overheating and burns before the plaintiff was hurt. When a manufacturer or a marketplace seller had notice of a burn pattern and kept selling, the failure-to-warn theory becomes the spine of the case.

The Deadlines: Four Years to Sue, Two Years if Someone Died

Get the clock right, because the wrong clock loses the case. A products-liability claim for personal injury in Florida has a four-year limitations period under section 95.11(3)(d), Florida Statutes, which covers injury founded on the design, manufacture, distribution, or sale of personal property. That four-year period is the one that applies to a burn from a defective heated product.

Do not confuse it with general negligence. Florida's tort reform, House Bill 837, took effect March 24, 2023, and cut the ordinary negligence limitations period to two years under section 95.11(5)(a). A products-liability claim still gets four years, but a claim pleaded only as negligence may get just two. Pleading the products theory matters for the deadline, not only the burden of proof.

Wrongful death is its own track. If a defective heated product killed someone, the estate has two years under section 95.11(5)(e), Florida Statutes. The Ocoopa hand-warmer fire that killed Sri Damajanti Sunarjo is a wrongful-death case, not a personal-injury case, and its two-year clock is the one that controls. When a death is involved, treat the case as a two-year case from the start.

One more deadline can bar an otherwise-good claim outright. Section 95.031(2)(b), Florida Statutes, sets a twelve-year statute of repose that runs from the delivery of the product to its first purchaser, regardless of when the injury happened. Most heated apparel is new and recently sold, so repose rarely bites here, but it matters for an older sauna unit or a gift bought years before the burn. Florida also applies modified comparative fault under section 768.81, Florida Statutes: a plaintiff found more than fifty percent at fault recovers nothing, which makes the manufacturer's likely argument that you misused the product worth taking seriously from day one.

Preserve the Product: It Is the Evidence

The single most important thing a burn victim does is keep the device. Manufacturers and Amazon will offer a refund or a prepaid return label. A refund extinguishes the proof. Once the unit goes back to the maker, an independent expert can no longer open it, and a manufacturing-defect theory can evaporate.

Keep the exact unit that burned you, the battery pack, the charger, the box, the manual, and the listing or receipt. If the device is a fire hazard, you can store a vented lithium cell safely while still preserving it; a lawyer or fire investigator can advise on safe storage rather than disposal. Photograph the device from every angle and the burns at each stage of healing.

Spoliation cuts both ways. If you discard the product, the defense will argue you destroyed the proof. If the manufacturer destroys returned units, that can support an inference against the manufacturer. Either way, the side that keeps the unit controls the narrative. Keep yours.

Who You Sue: Maker, Importer, and the Online Marketplace

These products usually have a chain of defendants, and the right strategy names all of them. The manufacturer is the first target, but in this niche the manufacturer is frequently a Chinese company that ignores the CPSC and cannot be served easily. Jining Liexing, the Velazzio maker, and Zhangfengqing, the iHeat maker, both went silent. That makes the domestic links in the distribution chain essential.

Amazon is increasingly a defendant rather than a bystander. Both the Vilaire glove lawsuit and the Tan hand-warmer wrongful-death lawsuit name Amazon entities directly, alleging Amazon distributed and logistically controlled the product and had notice of prior overheating reports. Where a brick-and-mortar retailer sold the unit, such as Costco for the 32 Degrees socks or Dick's for the Lifepro blanket, that retailer is a distributor in the chain and a proper defendant under Florida strict-liability law.

Naming the full chain protects the client against the disappearing-manufacturer problem and against finger-pointing among defendants. A judgment is only as good as a defendant you can collect from.

Practice Notes From Graham

I am Graham W. Syfert, Of Counsel to the Soud Law Firm. When you call about a burn, the phone rings to me, not a call center. I will want three things in the first conversation: where the product is right now, what the burns look like, and how you bought it.

I tell every heated-product client the same thing first. Do not accept the refund yet. The moment you send the device back, you have handed your best evidence to the company you are suing. Keep it, even if it is charred, even if Amazon emails you a return label twice a day.

I do not promise outcomes, and Florida Bar rules forbid me from doing so. Other plaintiffs have settled or are litigating burn claims against these makers and against Amazon, but every case turns on its own facts and its own product, and past results never guarantee a similar one. What I can promise is candor about whether your facts make a case and a clear explanation of the four-year products clock under section 95.11(3)(d), Florida Statutes, or the two-year wrongful-death clock under section 95.11(5)(e) if a death is involved. There is no charge to find out.

What to do now

If a heated product burned you or someone you love, the first hours matter for both your health and your claim. Take these steps in order.

  1. Get medical care and have the burns documented. See a doctor or a burn unit, even if the burn looks minor at first. Full-thickness burns can be deceptively painless. The medical record is the backbone of the claim, so be specific that a heated product caused it.
  2. Do not return or discard the product. Keep the exact device that burned you, the battery pack, the charger, the box, and the manual. Refuse refund offers and return labels until a lawyer has seen the unit. The product is the evidence.
  3. Store a fire-damaged device safely but do not throw it away. If a lithium battery vented or caught fire, store the unit away from anything flammable rather than discarding it. Ask a lawyer or fire investigator about safe preservation. Disposal destroys the proof.
  4. Photograph everything. Photograph the device from every angle, the model and serial markings, the battery pack, the packaging, and the burns at each stage of healing. Date the photos.
  5. Save the purchase record. Screenshot or download the Amazon order, the Costco receipt, or other proof of purchase, including the listing, price, and date. This pins down the seller and the timeline.
  6. Capture the product listing and any reviews. Save the online listing and any reviews describing overheating or burns. Prior complaints can support a failure-to-warn claim against the maker and the marketplace.
  7. Write down what happened while it is fresh. Note the date, the heat setting, how long the device ran, whether it was on or off, and exactly how the burn occurred. Memory fades; write it now.
  8. Call before a deadline runs. Florida gives four years for a products-liability injury claim under section 95.11(3)(d), Florida Statutes, and two years for wrongful death under section 95.11(5)(e). Call Graham W. Syfert, Esq., Of Counsel to the Soud Law Firm, to find out where your case stands.

Key statutes

Frequently asked questions

I was burned by a Lifepro Bioremedy infrared sauna blanket. Do I have a case?

Possibly. Lifepro Fitness recalled the Bioremedy infrared sauna blankets on October 23, 2025, after 65 overheating reports including 32 burn injuries. A burn from a recalled product is strong evidence of a defect. In Florida you generally have four years to bring a products-liability injury claim under section 95.11(3)(d), Florida Statutes. Keep the blanket and call before you accept any refund.

Costco recalled my 32 Degrees heated socks. Can I sue if they burned me?

Yes, a recall does not replace your claim; it supports it. David Peyser Sportswear, doing business as 32 Degrees, recalled about 207,806 pairs of heated socks on April 23, 2026 under CPSC recall 26-435 after 14 incidents and 13 first- or second-degree burns. You can return the socks to Costco for a refund, but if they burned you, keep the pair and the battery pack as evidence first.

My Velazzio Thermo1 heated gloves overheated and burned my hands. What can I do?

The CPSC warned on July 31, 2025 that Velazzio Thermo1 battery-heated gloves can overheat and burn the wearer, citing 137 overheating incidents and 119 burn injuries. The Chinese manufacturer did not agree to a recall, so the U.S. seller may be the key defendant. Preserve the gloves and the battery, document the burns, and ask about a Florida products-liability claim.

Are heated insoles like iHeat dangerous, and can I make a claim if mine caught fire?

Yes. The CPSC warned that iHeat heated insoles can have their lithium-ion battery ignite even when switched off, reporting 11 thermal incidents and 8 burn injuries, some second- and third-degree. Store the unit safely rather than throwing it away, because it is your evidence, and call a lawyer about a products-liability claim.

What is the deadline to file a heated-product burn lawsuit in Florida?

For a personal-injury products-liability claim, Florida gives four years from the date of injury under section 95.11(3)(d), Florida Statutes. If a defective heated product killed someone, the wrongful-death deadline is two years under section 95.11(5)(e), Florida Statutes. A separate twelve-year statute of repose under section 95.031(2)(b) can bar claims on very old products. Do not wait to find out which deadline applies to you.

Why should I not return the sauna blanket or heated socks for a refund?

Because the product is the evidence. Once you ship the device back, an independent expert can no longer open it to prove a manufacturing defect, and your strongest proof is gone. Keep the exact unit that burned you, the battery, the charger, and the packaging. A refund is small money next to a burn claim.

Can I sue Amazon for a heated glove or hand warmer that burned me?

Often yes. Recent lawsuits name Amazon directly. The Vilaire heated-glove lawsuit and the Tan wrongful-death lawsuit over an Ocoopa hand warmer both name Amazon entities, alleging Amazon distributed the product and knew about prior overheating reports. When the overseas manufacturer cannot be reached, Amazon and the retail seller become the defendants who can actually be held accountable.

A family member died from a hand warmer or heated blanket fire. What are our rights?

This is a wrongful-death case, and the deadline is two years under section 95.11(5)(e), Florida Statutes. In one filed matter, a daughter sued Amazon and Ocoopa after an Ocoopa rechargeable hand warmer allegedly ignited in bed and her mother died of the burns. The estate can pursue strict products liability, design defect, manufacturing defect, failure to warn, and wrongful death. Preserve the device and call promptly.

Does it matter that the heated socks or gloves were made in China?

It matters for strategy, not for your rights. Chinese makers like the Velazzio and iHeat manufacturers frequently ignore the CPSC and are hard to serve. That is why naming the full distribution chain, including Amazon and any U.S. retailer like Costco or Dick's, is important. Under Florida strict-liability law, sellers and distributors in the chain can be liable for a defective product.

Do I have to prove the company was careless to win a heated-product burn case?

No. Florida follows strict products liability, adopted in West v. Caterpillar Tractor Co., 336 So. 2d 80 (Fla. 1976). You must show the product was defective when it left the manufacturer and that the defect caused your injury, not that anyone was negligent. That said, Florida applies modified comparative fault under section 768.81, so a plaintiff more than fifty percent at fault recovers nothing.
