We read 5,262 heated-gear reviews. The battery is not the main problem.
Most one-star reviews never mention the battery at all. They say the heat sat in the wrong place, the gear quit in its first season, or it didn't fit. Here's what that means before you buy.
Buyer's guides
Each guide starts with what buyers complain about most, then the specs that fix it.
Field notes
Short, practical reads on the things the spec sheet won't tell you.
How we test
The same four questions, in the same order, for every product.
Is the heat where you're cold?
We count the zones, then map where they sit: neck, shoulders, lower back, front, fingertips.
What runs it, and what it costs to replace
Real capacity in watt-hours, whether it's in the box, and whether any USB bank works.
Does it fit like the size chart says?
Measured charts in US sizes beat "true to size." We check where buyers say it runs small.
What happens if it isn't warm enough?
Returns, guarantees and how a brand treats you when something stops heating.
A heated vest that heats one patch of your back is a fleece with a battery in it.
Winter Tested started with a simple frustration. Every heated jacket listing promised all-day warmth, and the reviews told a different story: cold fronts, dead batteries, zippers gone by February.
So we stopped reading listings and started reading buyers. Thousands of them, one review at a time, sorted by what actually went wrong.
What came out is a short list of questions that separate the gear people keep wearing from the gear that ends up in a drawer. Every guide on this site is built on them.
We're adding categories through the season. If there's something you want us to look at, write to us.
