Sea To Summit Womens Comfort Light Self Inflating Mat - 2 Sizes

$189.95 CAD 985986

Engineered to provide comfort and warmth to women adventurers wanting to travel lightly, the Women’s Sea to Summit Comfort Light Self-Inflating Sleeping Mat is constructed with warmth zones in the hip and foot area to provide extra support and insulation where women need it most. Silicone prints on the upper surface prevent your sleeping bag from slipping, and the flip-over multi-function valve makes rolling up the self-inflating sleeping pad quick and easy.

Wider through the shoulders and hips than a traditional sleeping pad, the shape enhances comfort for those who sleep in a figure-4 position or move frequently through night making it easier to stay on the wider surface area throughout the night.

30D Polyester TPU

Ever woken up cold because you slipped off your sleeping mat in the middle of the night? Not any more. Select models in our S.I. mats have anti-slip silicone print patterns to help your sleeping bag stick to your mat, & your mat to the tent floor.
Sea to Summit have innovated to to make their range of Self Inflating mats thicker, lighter and easier to use. That innovation is Delta Core Technology. This technique reduces the volume of the foam by up to 40% which in turn reduces the packed weight and size of the mattress. The biggest advantage of the Delta Core technology is that it keeps the top and bottom surface of the foam in one piece, this ensures the mat is consistently warm along the full length of the mattress. 
We have literally put a new twist on our very successful multi-function valve so it specifically addresses the inherent characteristic of self-inflating mats-that is, the problem of the foam trying to re-inflate as you’re packing up.  

The Pillow Lock System
Comprises of self-adhesive hook-and-loop patches which are supplied with all Sea to Summit sleeping mats (as of Spring 2019),

Attached to your sleeping mat, these patches secure your pillow and prevent it slipping – yet they will not snag on clothing or other lightweight fabrics. All Sea to Summit Pillows (as of Spring 2019) are compatible with this system. Existing pillows can be made Pillow Lock™ compatible by adding an Aeros Pillow Case. 

ASTM F3340-18 test to provide R-Values for our mats.
This new testing standard has been driven by industry leaders (including Sea to Summit) wanting to achieve two things:

1. Provide clarity and transparency to consumers

2. Create a universal system to enable users to compare mats across brands.
