Sea To Summit Alpine -29°C is a mummy sleeping bag designed to keep you warm even in the harshest weather conditions.
Meticulously designed, Alpine is filled with RDS certified goose down and treated with the eco-friendly Ultra-Dry Down treatment to provide maximum performance even in wet and humid conditions.
Additionally, its insulation has a fill power of 850+ which indicates that one ounce (30 g) of down will expand to over 850 cubic inches after compression. A higher fill power means that less down can be used to achieve the same temperature, which is important for high-performance sleeping bags.
The details have been studied and tested over the years: expedition mummy shape to accommodate gear you don't want to leave outside, hood with collar to retain heat that can accommodate a pillow, side zipper closure (compatible with all Sea To Summit women's models) with an additional zip covering 1/3 of the length to adjust internal ventilation.
