The Ascent -1C Down Sleeping Bag by Sea to Summit is for the minimalist adventurers and all-out explorers!
A 3°C comfort rating and -1°C lower limit has it suitable for cold-weather camping, while the Free Flow Zip system features durable #5 full-length primary, half-length secondary, and footbox zippers, finished with zip plows, sliders, and a down-filled draft tube for easy, snatch-free use. Minimise cold spots thanks to vertical and horizontal chest baffles are present in both the lower-half and base, while box-wall baffles exist throughout the construction of bag. Plus, a fitted front collar draft helps to trap heat, while the hood offers a soft-touch adjustment and generous room for a regular-sized Sea to Summit pillow.
A Mummy Fit offers both a relaxed fit and thermal efficiency on those wildlife wanders, while the 20D Nylon shell and lining works with the 10D Nylon hood and footbox for lightweight breathability and water resistance on every outdoor retreat. Plus, RDS certified 750+ FILL Power goose down provides both comfort when unpacked and a compact pack down, treated with ULTRA-DRY down water-repellent to protect from moisture on the damper days off the grid.
The Sea to Summit Ascent -1C Down Sleeping Bag offers maximum warmth on every outdoor escape.
