Sea to Summit Comfort Light Sleeping Mat

This mat features specialized Delta Core technology that provides extra insulation and support in the hip and foot areas, where women typically experience more heat loss and pressure points while sleeping.

With an R-value of 3.8, this mat is well-suited for three-season camping. It provides enough insulation for cool spring and autumn nights, though it may not be sufficient for deep winter conditions.

When you open the multi-function valve, the open-cell foam inside expands and draws air in automatically. You can then use the valve to top it off with a few breaths if you prefer a firmer feel or to make micro-adjustments to the pressure.

Unlikely. The surface is treated with a silicone print designed specifically to grip the bottom of your sleeping bag, keeping you centered on the mat even if you toss and turn.

It features a PillowLock system, which uses hook-and-loop patches to secure compatible Sea to Summit pillows in place. If you use a different brand, the pillow will simply rest on top without the locking mechanism.

The mat includes a repair kit, which allows you to patch small punctures or leaks on the go. It is a straightforward process, but it is worth practicing the repair once at home before your first trip.
