When you're up high and the temperature dips low, there's no other option than to hunker down in the Sea to Summit Ascent™ 0 Sleeping Bag. With a lightweight nylon shell and ultra-dry down insulation, this bag packs down small and doesn't weigh you down. The relaxed mummy outline with shaped hood and oversized draft collar allows you to sleep comfortably without compromising warmth, while the free flow zipper offers additional ventilation and temperature regulation.
Lightweight 20D Nylon Shell
Ultra-Dry Down 750+ Loft – 90% Down Cluster Premium Duck Down
Compressed Volume, Long – 10.2 L
Compressed Volume, Regular – 8.2 L
Relaxed Mummy Shape – More room between hips and knees to allow you to sleep in a natural position without compressing the down insulation and creating cold spots. Far more comfortable than narrow mummy bags for most sleepers.
Free Flow Zip – The half-zip on the right side of the bag (left side on women's bags) provides freedom of movement for both arms, additional ventilation and allows the top third of the bag to be folded down as a mini quilt when the mercury climbs higher than expected.
