Ocoopa 2 Pack 5000mAh Hand Warmers Rechargeable,Winter Gifts for Men,Women,Christmas

These handwarmers warm up very quickly and are perfect to put in your pockets to keep your hands warm during chilly nights, especially out camping. The simple heat settings make it easy to get just the right temperature in your pockets to keep your hands warm.

I got this to keep my hands warm working in freezing temperatures. These are good for putting them in a glove vs holding it like one of the bulkier ones, they are about the size of a hot hand packet. Using it is pretty simple too and so far the heat is really nice, the low setting you can keep directly on your skin and the medium high setting will penetrate through a cloth. The fact it's magnetic to keep them together is cool too and I like the dual single charger since I can use that for other things too. If you want something smaller you can keep in your hand easily while doing stuff this is better than one of the ones the size of your hand.
