I commute year round, but when the temperature dips below 20 degrees F, my thumbs really complain. I use thick fleece gloves (Arc'Teryx Delta AR) with Burton snowboard mittens over them now. This is fine except for those super cold days.
I've been looking at heated glove liners (rechargeable). Looks like these are in the $100 - $200 range. But there are so many brands, and not a lot of reviews or comparisons. Can anyone recommend a reliable brand? Or brands to avoid? Thanks!
