Mountain Equipment Snowline

Mountain Equipments lightest expedition class sleeping bag. Ultralight when used alone but with enough room to accommodate clothing when pushed to its absolute limit.

For use in extreme conditions below -18°C / 0°F, these bags are outside the scope of the EN13537 test. Please refer to Mountain Equipments Good Night’s Sleep Guarantee rating.

Engineered to withstand extreme cold in the most hostile environments on earth. With durably rain-resistant fabrics and construction optimised to maximise and maintain warmth for extended periods these bags are built specifically for the needs of explorers and mountaineers undertaking the most committing journeys in the highest, coldest and most remote locations.

Vertically aligned V-baffles on the chest and foot piece, 14:7cm Trapezoid baffles throughout all other parts of the bag, a 6 baffle foot piece and a 7 baffle hood results in minimal down migration and maximum possible warmth in all situations.

A lower density V-block side baffle maximises thermal resistance by preventing the migration of down away from the top of the bag, but it is kept as light as possible to reflect the reduced heat losses which occur at the sides of a bag. The use of ground level side-seams helps concentrate 50% of the bag’s down volume in the top, with approximately 30% in the bottom of the bag. Despite these differences in percentage fills, the densities of down are greater in the bottom of the bag, hood, undersides of the bag, and the foot piece, to reduce moisture and down migration.

For use in extreme conditions below -18°C / 0°F, these bags are outside the scope of the EN13537 test. Please refer to our Good Night’s Sleep Guarantee rating.
