I found a bunch of electric and reusable gel type hand warmers. It looked like the electric ones were too large, but could be used as battery backups for the phone. And if the gel pouches are anything like the cold-packs I've got perpetually in the freezer, I worry that they won't hold much heat.

Does anyone have a recommendation for a small hand-warmer that could replace the chemical pouches?

We purchased 2 of the electric hand warmers on Amazon, they are about the size of a pack of cigarettes, they also double as a accessory battery pack, 10,000 mhr. Under $20. They have 3 settings, we use the low, med and high are way too hot. I rotate jacket pockets, when my hands start to get cold I just stick my hand in my pocket for a few minutes. If my core start to chill I put it in my shirt pocket and zip my jacket all the way. This thing really throws some heat. Put it in my sleeping bag and get nice and toasty. Too much heat to leave on all night. Runtime over 8hrs. on low! Recharges overnight. The only drawback......weight. A great trade off to stay warm.
