The Sea to Summit Comfort Plus Self Inflating Mattress offers both warmth and luxurious cushioning. It is a 3+ season mat with an R-value of 4.1, which is also warm enough for mild winter nights.

For better insulation directly underneath you, the PU foam is thicker on top. It also keeps the top and bottom foam layers intact, ensuring even warmth along the length of the mat and a better bond with the upper fabric. Diagonally supporting foam walls help inflate the Comfort Plus Self Inflating Insulation Mat from Sea To Summit and create a compact rolled mat.

Delta Cores reduces the original volume of the PU foam by 40 % and allows the weight and pack size of the sleeping mats to be minimized as much as possible.

Features:
• 4.1 R-Value is warm enough for all but the coldest ground.
• Three inch thick foam and knitted polyester upper face fabric provides for an amazingly comfortable night’s sleep.
• Delta Coring removes over 40% of the foam to reduce weight and bulk, without compromising durability.
• Woven 30D polyester face fabric has been chosen for its light weight and strength.
• Silicone print prevents your sleeping pad from slipping on the tent floor.
• Flip-over multi-function valve for fast and easy inflation, deflation and fine-tuning of air pressure.
