Amazon Heated Underwear Lawsuit Claims Electric Garment Caused Severe Burns

Lawsuit claims heated underwear sold on Amazon was defectively designed and prone to overheating, which resulted disfiguring injuries.

A Pennsylvania man has filed a product liability lawsuit alleging that heated underwear he purchased on Amazon overheated while he was wearing it, causing severe burns and other permanent injuries.

The complaint (PDF) was brought by Nicholas Evangelista in the U.S. District Court of Pennsylvania on May 27, naming Amazon.com Services LLC as the only defendant.

Evangelista alleges he was wearing the Savior heated underwear while shoveling snow, but instead of keeping him warm, the product overheated and caused severe burns, which left him permanently disfigured.

Heated Apparel Burn Injuries

Savior heated underwear comes equipped with electrically heated coils, which is intended to be worn under clothing to help keep the user warm. However, Evangelista’s lawsuit joins a series of complaints filed in recent months over various electrically heated garments. Many of these filings allege that battery-powered devices meant to provide comfort have instead caused fires, severe burns and other lasting harm.

A number of recent heated insole lawsuits claim that inadequate safeguards in foot warmer devices have allowed those products to overheat while being worn, leading to serious burn injuries that often result in nerve injuries and surgical debridement. Many of these claims focus on Amazon’s role in selling and distributing heated socks and other battery-powered warming apparel.

Heated Underwear Injury Allegations

According to the lawsuit, Evangelista purchased a pair of Savior heated underwear in December 2025 and wore the product on February 9, 2026, while shoveling snow. During use, the underwear allegedly overheated without warning and reached extreme temperatures, causing serious burns to his body.

As a result, Evangelista claims he suffered painful burn injuries that left him permanently disfigured. The lawsuit indicates he experienced skin discoloration and hyperpigmentation, as well as disability, mental anguish, embarrassment, humiliation and a reduced ability to enjoy daily life. He also required extensive medical treatment for his injuries.

The complaint alleges the heated underwear was defectively designed and unreasonably dangerous, and that Evangelista’s injuries could have been prevented if safer design features or adequate safeguards had been used.

The lawsuit further claims Amazon knew or should have known about the alleged defect, but negligently allowed the heated underwear to continue being sold through its website, exposing consumers to a risk of serious injury.

“The Heated Underwear failure was such that would not have occurred in the absence of a defect or unreasonably dangerous condition within it.”
