The Ascent -1C Down Women’s Sleeping Bag by Sea to Summit is specifically suited to the women, offering superior warmth and lightweight comfort on every minimalist adventure.

A -1°C comfort rating and -8°C lower limit has it suitable for the icy, sub-zero blasts beyond suburbia, 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 women-specific Mummy Fit offers both a relaxed fit and thermal efficiency on those wildlife wanders, designed to be wider at the hips and narrower at the shoulders to retain heat and accommodate the female body’s requirements in colder climates. The 20D Nylon shell and lining works with the 10D Nylon hood and footbox for lightweight breathability and water resistance on every outdoor retreat, while 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.

Featuring a QuickLock system for easy attaching to separately available Sea to Summit quilts too, enjoy versatility on every adventure with the Sea to Summit Ascent -1C Women’s Down Sleeping Bag.
