Description

Weight is everything for a summer alpinist and the pursuit demands a bag that is as light as possible without compromising the critical features required for long ascents at the limit of endurance. The Direct Ascent sleeping bag is equipped with a technical hood and designed to allow a snug fit that moves with the head both when lying down and sitting upright. Its ergonomic body shape reduces cold spots and helps deliver more a comfortable sleep, while the technically engineered foot box has the space to allow a relaxed foot position and extra layers of tent footwear. The super light PERTEX® Quantum outer shell provides windproof and breathable protection for the down, while its renowned durable water repellency helps shed any tent condensation.
