The Ascent is Sea to Summit's most versatile sleeping bag. This three-season sleeping bag is filled with 750+ fill power RDS-certified goose down, with a PFC-free Ultra-Dry Down treatment. Not only does it provide you with excellent thermal comfort in the coldest conditions, but you'll also stay drier in humid environments.
The innovative Free-Flow Zip system allows for multiple zipper configurations, facilitating optimal ventilation and even allowing you to fully open it to use as a duvet on warm nights. Plus, it includes shoulder snaps to adjust it while you hike with it.
The mummy-style design ensures efficient heat distribution and added comfort. It also features a hood space to accommodate an Aeros pillow, and is compatible with most Sea to Summit women's sleeping bags.
Vertical torso and box-shaped baffles minimize down shifting, maximizing heat retention.
The outer shell of the Sea to Summit Ascent sleeping bag is made from 20D recycled nylon with a PFC-free DWR finish, which protects against wind and moisture. In addition, the interior is also lined with 20D recycled nylon for added comfort.
