Solio's solar-powered chargers ($99.95) will keep campers' cameras clicking and ice climbers' iPods humming. They also sell a range of useful chargers, cases and adapters to make any outlet-free expedition more convenient.
The online handmade wonderland known as Etsy has a great collection of warm hats and scarves for the winter-lover. Browse like crazy, or try a cute and cuddly scarf ($35-$95) from YoKNITS, to warm the extremities of your favorite skier or snowshoer.
Winter is more enjoyable when you're warm and dry (and when the powder is perfect, and the sky bright blue and the mountain open and glistening before you). For the adventurer who hates being cold, we suggest Capilene long underwear ($38-$120). Patagonia's Capilene is made from recycled materials -- and that's something to feel warm and fuzzy about.
