Details & Specs
Lightweight yet warm and versatile, the Ascent Ac1 from Sea to Summit is an adaptable down bag which will keep you comfortable on all kinds of adventures.
This bag has a tapered rectangular shape which is roomier than a mummy bag but will still keep you warm. You can adjust this design depending on the conditions thanks to the free-flow triple zips. With a half zip on the right side you can fold it down to free up your arms, the full-length zip and separate foot zip allows you to use it as a quilt when it’s hot, and you can close it all up when it’s chilly. The Ascent Ac1 has a 2°C comfort rating and -4° lower limit so it’s suited to general 3 season use.
Filled with R.D.S certified 750+ loft down, this bag provides plenty of insulation and it has vertical baffles over the chest to prevent cold spots, a side block baffle to keep the 60/40 fill ratio and oversized draft tubes to trap body heat. To keep the weight down, the shell and lining are made from breathable yet lightweight nylon, while the large internal security pocket means you can keep your valuables close as you sleep.
Prepare yourself for a myriad of sleeping conditions, with the cleverly adaptable Ascent Ac1 Sleeping Bag from Sea to Summit.
