If you’ve worked with other outdoor gear, you know it’s impossible to pitch a tent or start a fire with cold hands. It’s also difficult to do both of those things with gloves. And sometimes, gloves themselves aren’t enough and you have to grab a pair of the best hand warmers. Disposables are convenient, but wasteful and expensive, sp consider a pair of rechargeable hand warmers. Our favorites from OCOOPA are super-cheap for October Prime Day, aka Amazon Prime Big Deal Days.
