Mammut Tubular Dyneema 8mm Contact Slings are the ultimate slings for super-light alpine climbing or simply shaving ounces off your rack. What makes them so special? They weigh next to nothing, don't absorb water, don't freeze, and are more abrasion-resistant than nylon. Use the 60cm length for over-the-shoulder slings, the 120cm length for tying off horns and chockstones, and the 180cm length for an ultralight cordelette.
