Forget about fixing absolutely everything with duct tape. On your next trip, bring along the S.O.L. 3, a medical/survival kit ($56, adventuremedicalkits.com) that goes above and beyond. The zippered, clamshell-style bag has two compartments: one for medical supplies and the other for survival tools and other gear, including everything from bandages and ibuprofen to a compass and headlamp. The full kit weighs 1 lb. 5 oz., and there’s a detachable pouch to hold bare essentials during climbs.
