Product Info


The Ascent AcII offers the perfect backpacking balance of comfort vs weight and has more space than traditional mummy bags without compromising on thermal efficiency.

The Free-Flow triple-zip design ensures this sleeping bag retains maximum warmth and efficiency when needed and multiple ventilation options when it’s not. The half zip on the right side of the bag provides freedom of movement for both arms, additional ventilation and means the top third of the bag can be folded down as a mini quilt. The full length, two-way left side zip and separate foot zip also transforms the bag into a full quilt.

The vertical baffles over the chest section ensure the down insulation cannot migrate or shift to the outside of the bag during sleep, creating cold spots. Panelled footbox and 3-dimensional hood make sure you’re not compressing the down when you’re trying to stay warm and the side block baffle construction maintains the 60/40 fill ratio, keeping more down on the top of the bag for maximum insulation.

Large internal security pocket keeps essentials safe and to hand and the Ultra-Sil compression bag allows for compact storage.
