The Mammut Sphere Bivi is an uncompromising, very lightweight bivy sack that should be part of every tour. It features attachment openings, a drawstring, and an integrated stuff sack. The top is made of a breathable membrane with a water column of 15,000 mm and a moisture permeability of M/P 15,000 g/m²/24h. The bottom is made of a waterproof nylon fabric with a water column of 5,000 mm. Mammut advocates for fair working conditions throughout the entire manufacturing chain, and suppliers are systematically monitored. The independent Fair Wear Foundation verifies Mammut's practices. The fabrics of the compact sleeping bags are produced according to the strict bluesign system. As a result, one in four sleeping bags sold by Mammut is made from materials that optimally consider the impact on people and the environment during the manufacturing process.
