Why We Like The Sea To Summit Ascent Sleeping Bag
The Sea To Summit Ascent Sleeping Bag is the ultimate sleeping bag for versatile adventures, offering a spacious mummy shape for comfortable nights and lightweight design that keeps our pack light while backpacking through the high country. The hydrophobic down provides lofty warmth in damp conditions, allowing us to get out there in early spring when there´s still snow melting away in the mountains. The Free Flow Zip System allows for fully customizable warmth, with the full-length main zipper, half-length side zipper, and zippered footbox allowing us to configure the bag for precise comfort.
