I keep a couple packs in my ski pack (usually ski about 30-45 days a winter with a mix of inbounds and backcountry) and use them quite a bit for my hands with good results. As far as in the bag I like them as well and believe a couple packs is worth the weight . The water bottle as said works but for me is way to bulky in my already narrow foot box mummy bags.
