ULTRALIGHT INSULATED

Features

• 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.

Sea to Summit developed the XPRESS Valve to make inflation, deflation and adjustment of its air mats quicker and simpler than conventional air mats. The valve integrates a one-way inflate port, a rapid dump deflate port and a fine-tune button into a single, low-profile unit. The XPRESS valve fits the nozzle of the Airstream pump integrated into the stuff sack supplied with your Sea to Summit Air Sprung Cell sleeping mat.

(Pro Tip-turn the inflator bag of the sleeping mat pump inside out to reveal a nozzle sized perfectly for the mini-XPRESS valve of an Aeros Pillow)

Air Sprung Cells are the core technology used in Sea to Summit Air Mats and are the reason you will sleep more comfortably on a Sea to Summit mat than on a conventional air pad.

Inspired by the hundreds of springs found in a modern pocket sprung mattress, the hundreds of small interconnected chambers (called Air Sprung Cells) perfectly support your weight and conform to your body contours.

The Ultra Light range has a single layer of medium resolution cells to give you the lightest and smallest packed volume mat without compromising on Sea to Summit's Air Sprung Cell comfort.

The Airstream Pumpsack is Sea to Summit's big volume mattress pump which we've now integrated into the stuff sack of every Air Sprung Cell mat.

The clever design opens at one end to stow the air mat and the other end unfolds to become the built-in pump. The Airstream Pumpsack can be inflated with a single breath and takes just two or three cycles to fill our mats. Not only is it faster than inflation by mouth, but there is minimal breath condensation entering the mat and it eliminates dizziness from blowing the mat up directly by mouth.

The Airstream Pumpsack is also compatible with Sea to Summit's smaller multifunction valve, which is now featured on the updated Aeros pillow range, along with the Air Seats.

To ensure that you will be warm when you sleep (especially when the ground is colder), it is essential to know how well your sleeping mat resists heat loss into the ground. This resistance is known as an R-Value. A laboratory-tested R-Value is the only way to measure resistance to heat loss

Sea to Summit has always provided independent lab-tested R-Values for its sleeping mats. Since January 2020 we have used the industry standard ASTM F3340 test to provide R-Values for our mats.

There are several other factors which will determine how well a sleeping mat will insulate, but the standardized ASTM R-Value test means you can compare resistance to heat loss in sleeping mats across different brands
