Sea To Summit Altitude II Women's Down -10° Sleeping Bag Regular Blue Ocean & Arctic

Offering the perfect backpacking balance of comfort and weight, the Sea To Summit Altitude Series sleeping bags have more space than traditional mummy bags, yet still provide the thermal efficiency you need when exploring above the tree-line. The women specific fit design feature a comfortable tapered shape which is narrower at the shoulders and wider between the hips and knees, additional insulation compared to unisex bags, a snug-fitting 3-dimensional hood, oversized draft tubes to prevent body heat escaping, and super-soft fabric. Vertical baffles over the chest section further ensure the down insulation cannot migrate or shift to the outside of the bag during sleep, creating cold spots. A side block baffle construction maintains the 60/40 fill ratio, keeping more down on the top of the bag for maximum insulation. The Altitude also features extra down overall and THERMOLITE? panels under the foot area, to help keep heels and ankles warmer.

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