Gloves or no gloves, hands can get cold when snowboarding on really cold days or in really crappy weather. Air-activated hand warmers can give the gift of warm hands in even the coldest conditions. These simple, single-use packs heat up when the package is opened to expose them to the air, and will remain hot, thus effective, for up to 10 hours. To keep your hands warm, you can either put them down into your gloves or hold them in your ungloved hand. It only takes these handwarmers 15 to 20 minutes to reach a maximum warmth of 150 to 160 degrees. In fact, air-activated handwarmers are a great gift for not only snowboarders, but also for skiers, hunters, anglers, hikers, campers, backpackers and many other outdoors lovers.
