STS Ultralight Insulated Mat-S

The Air Sprung Cell design delivers stability and support, while our lamination and weld quality set a new standard for reliability. What's more, Thermolite® and Exkin Platinum® insulation deliver the warmth of an ASTM standard R-Value of 3.1 - just perfect for late spring through to early fall camping.

• 3.1 R-Value is sufficient for late spring to early fall use.
• Exkin Platinum® insulation reflects your radiant heat back to you, while Thermolite® insulation prevents convective heat loss.
• Lighter, quieter and durable 30D/40D face fabric with Sea to Summit’s liquid-extruded lamination is extremely reliable.
• Quick and easy inflation, deflation and adjustment is made possible by our multi-function valve and supplied Airstream Pump/stuff sack.
• Anti-microbial treatment added to the TPU lamination formula prevents internal mold growth.
• PillowLock system prevents your Sea to Summit Aeros Pillow from slipping.
• Comes with a stuff sack which doubles as a pump, a repair kit with six self-adhesive patches and a spare valve insert.
• Airstream Pump/Stuff Sack can be used to inflate Aeros Pillows – turn the inflator bag inside out; the nozzle will fit the mini pillow valve.
