Sea To Summit Women's UltraLight Insulated Mat

This mat features a tapered shape that is wider at the hips and narrower at the shoulders, which is specifically engineered to accommodate the typical female sleeping position and body geometry. It also includes extra insulation to provide a higher level of warmth where women tend to lose heat most quickly.

An R-value of 3.5 is ideal for three-season use, meaning it will keep you comfortable during spring, summer, and autumn adventures. While it provides excellent insulation for typical backpacking trips, it is not intended for deep winter or sub-freezing mountaineering conditions.

The pump sack attaches directly to the valve, allowing you to inflate the mat by capturing air in the bag and pushing it into the pad. This method is much faster than manual inflation and prevents moisture from your breath from building up inside the mat, which helps keep the interior clean.

Yes, it features the PillowLock system. This consists of hook-and-loop patches that allow you to attach a compatible Sea to Summit pillow directly to the mat, preventing it from sliding around during the night.

The mat includes a repair kit with adhesive patches and a spare valve insert, allowing you to make quick field repairs. It is a good idea to practice using the patches at home so you are comfortable with the process before you head out.

No, Sea to Summit uses a specific face fabric designed to be quiet. Unlike some ultralight mats that have a crinkly, plastic-like sound, this fabric is soft and minimizes noise when you shift positions.
