Thanks! And in terms of heated glove/mitten tech, have a pair of heated mittens already, the Thxtoms brand (although, they're discontinued): https://www.amazon.com/dp/B0CDLN91CN

The tech definitely works, and these were, at the time, just another relatively-cheap, but decently-well reviewed pair. Yeah in fact, on their own, they aren't that thick or durable, but when the heat is turned on, they are plenty warm. Seems like almost any decent pair of heated mittens/gloves would work well.

For me at least, the iron-oxide heat-packs work pretty well too, but they typically don't heat the fingers too well, so when its really cold, the main parts of my hands are warm, but my fingers aren't. It's not that bad, and it's easy to heat up the fingers by curling them around the heat pack, but with a heated glove, the heat typically reaches the fingers, so you don't really have to do anything and can just completely forget about your hands - but yeah, if I was loosing gloves often, maybe heated gloves would be a net waste compared to heat packs:)

Recently, bought a pair of heated liners to go under an oversized pair of gloves - I have Leki ski-gloves that directly attach to the ski poles, and they don't currently have a heater option, so am trying this instead. This are the heated liners: https://www.amazon.com/dp/B082XXKXCP

They're nothing special, but by my initial tests, they seem pretty warm under my gloves. Will know more tomorrow:)
