Whether you're headed out on a multi-day backpacking trip or are off on a weekend camping getaway, getting a good night's sleep is important so you can get the most out of your days. The Sea to Summit Comfort Lite Insulated Sleeping Pad is designed for comfort, warmth, and stability to help you rest easy in the backcountry. It is constructed with 324 individual air-filled springs that support your weight and conform to your body to keep you comfortable throughout the night. Its Thermolite insulation and Exkin Platinum fabric combine to prevent heat loss to give the pad an R-Value of 4. 7 allowing you to sleep on all but the coldest grounds. The pad is easy to inflate, deflate, and adjust as well thanks to the multi-function valve and Airstream Pump. The pump allows you to fill the pad in just a few breaths so you don't get dizzy and also reduces condensation entering the mat for added warmth.
