Description

The Ascent Women's -9C/5F Down sleeping bag for women from Sea To Summit is the perfect sleeping bag for short adventures.

This model is part of the Wayfarerrange, offering durable products that are easy to carry on your adventures. Lightness and reliability are two key qualities.

Ascent -9C/15F Down gives you the ability to use it all over the world and accompany you on all your adventures. To achieve this, this bag is made from RDS 750+ duck down and a Ultra-Dry Down treatment for better insulation and compressibility. It has vertically-positioned padding around the chest to prevent the down from moving and ensure even protection and a good supply of warmth.

This model has a two-wayFree Flow zip for better air circulation and ventilation when the weather warms up. There's a main zip running the full length, and a second half-length zip on the other side. The foot zip also has two zippers. A spacious design, a drawcord adjustment at the collar with space for a pillow and the Technical Regular Hood are the extra details that will make all the difference to your comfort.

Finally, this version has a Mummy Fit shape specially designed for women, providing better thermal performance with good heat retention.

Ascent Women's -9C/15F Down is a warm, comfortable and adaptable sleeping bag for a comfortable night's sleep!
