I'm in the market for some heated ski gloves. Cold hands while skiing have always been a problem for me. And yes, I know all the hooha about keeping your core warm, etc...... I'm tired of screwing around with the grabber warming packets so I've been toying with the idea of battery heated gloves for a couple of years but I always see lukewarm or bad reviews for them. In any case, I was thinking of the Black Diamond Cayenne or the Chaval Response XRT. Chaval looks like a new brand with a supposedly new technology. https://www.chavalusa.com/ Their website says that their gloves will last 3 times longer than the Cayenne and any other brand which is interesting. Can anyone here verify this? Does anyone have any experience with these or any other heated gloves? Especially the higher end ones? Thanks..
