HotHands Super Warmer

The best way to endure cold temperatures when your sleeping bag is not good enough.

This is a review of "HotHands Body & Hand Super Warmers - Long Lasting Safe Natural Odorless Air Activated Warmers - Up to 18 Hours of Heat - 10 Individual Warmers." 

Recently took up snow camping. Discovered my 5°F sleeping bag did not keep me warm at 8°F to 16°F despite sleeping pads over 8 R rating, a good 4-season tent, synthetic thermals, down socks, down pants, down jacket, and a wool baclava.

First my feet got cold early on. Put one warmer under my toes in each down sock. Went back to sleep and woke up about 0200 with a cold chest. Put one warmer in each pocket of my down vest. Now I was too warm. Had to unzip my mummy bag a little to let some heat out.

Woke up at dawn, had that wonderful cozy feeling you get sleeping by a fire.  Amazingly, the warmers kept warming me until late that afternoon. My take—try these warmers before you buy a new winter bag. Easy to pack, inexpensive, and they work.
