Sea To Summit Ascent -1°C

Our most versatile sleeping bag is designed for various temperatures. In colder conditions, you can cinch the technical hood, secure the protected zippers with a drawstring, and rely on the 750+ Ultra-Dry goose down to stay warm. In warmer weather, the Free-Flow Zip System allows you to open the zippers in different configurations for optimal ventilation, and you can even fully open it to transform the Ascent sleeping bag into a blanket for the warmest nights. These features make the Ascent a true three-season backpacking sleeping bag, of which there are very few on the market. Snap the buttons at the shoulders, unzip the foot area, and wear the Ascent around camp – hardcore adventures don’t always have to be hard.
