Overview

A lightweight down bag that packs serious warmth for the coldest nights

The Ascent AcIII -18°C Sleeping Bag from Sea To Summit combines Ultra-Dry treated 750+ loft down with a lightweight 20D nylon shell, making the Ascent series a firm favourite for perfectly balanced backpacking trips when the weather could get cold. The Free-Flow triple-zip design ensures your sleeping bag retains maximum warmth and efficiency when needed and multiple ventilation options when it's not. The half zip on the right side of the bag provides freedom of movement for both arms, additional ventilation and means the top third of the bag can be folded down as a mini quilt. The full length, two-way left side zip and separate foot zip transforms the bag into a full quilt for when the mercury climbs higher than expected.
