I'm a motorcyclist, and this is the best bit of kit I've ever bought. It's so thin it fits perfectly under my leathers without bunching. The 9 heating zones keep my core toasty, which stops my hands from freezing. 10/10.

My office is an icebox. I bought this, and it's the best thing ever. It's so thin I can wear it under a blazer, and no one knows. The 'low' setting is perfect for 8 hours of gentle warmth. I'm finally productive.

I hate winter because I hate feeling like the Michelin Man. This vest is the solution. It's ultra-thin, but on 'High', it's incredibly warm. I can wear this under a light jacket and be toastier than I was in a giant parka.

This is perfect for those dark, frosty morning dog walks. It heats up in about a minute. The 9 zones are great, especially the neck heater. The battery lasts me all week.

I work in construction, and this has saved me this winter. I wear it on 'Medium', and the 8-hour battery gets me through the whole shift. It's so thin I have full mobility.
