Sea To Summit Ascent Ac2 Sleeping Bag (−4 °C)

Versatile, comfortable and light – the Ascent Ac2 Sleeping Bag from Sea to Summit is the adaptable choice for accompanying you on different kinds of adventures.

This bag has a tapered rectangular shape which is roomier than a mummy style bag but will still keep you warm. It’s easy to adjust the Ascent depending on the weather as it has free-flow triple zips. The half zip on the right side allows you to fold it down to free up your arms, the full-length zip and separate foot zip means you can use it as a quilt in warm conditions, and you can zip everything up on a chillier evening. The Ac2 has a -4°C comfort rating and -10° lower limit so its suited for colder sleepers and use in cooler conditions.

The shell and lining are made from lightweight nylon to keep the weight down, and it’s filled with R.D.S certified 750+ loft down for plenty of insulation. It’s got 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. You can also keep your valuables close as you sleep in the large internal security pocket.
