About The Product
Sleeping well when you're backpacking goes hand-in-hand with sleeping comfortably. The Comfort Light Insulated Sleeping Mat uses Air Sprung Cell technology and a hybrid matrix of offset cells to provide amazing stability and comfort. A double layer of cells in the torso increases warmth, while a single layer of cells in the head and legs reduces weight.
Thermolite® and Exkin Platinum® are used to optimize heat retention and the multi-function valve enables simple inflation, deflation and the ability to fine-tune your personal comfort level. What's more, the uprated 30D/40D face fabric is quiet and durable, while the lamination technology continues Sea to Summit’s class-leading reliability.
Product Features
- 3.7 R-Value is warm enough for all but the coldest ground.
- Exkin Platinum® insulation reflects radiant heat, while Thermolite® insulation prevents convective heat loss.
- Hybrid-Layer Air Sprung Cells provide more support, insulation and comfort in the torso.
