Perfect balance of comfort, warmth and weight
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.

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.
- Quick and easy inflation, deflation and adjustment is made possible by our multi-function valve and supplied Airstream Pump/stuff sack.
- Lighter, quieter and durable 30D/40D face fabric with Sea to Summit’s liquid-extruded lamination is extremely reliable.
- 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.
Technical Features
HYBRID LAYER AIR SPRUNG CELLS
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 Comfort Light series of mats has an internal layer of 40 D Nylon in the torso section. This allows the welds of the lower and upper cells to be offset, resulting in a greater number of cells in this area for greater support and insulation. The cells in the head and leg sections of the mat do not have this internal layer, which saves overall weight. This hybrid construction (two different weld patterns) may be the perfect option for an end user looking for more comfort and insulation without adding to much weight.
INTEGRATED AIRSTREAM
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.
ASTM F3340-18 R-VALUE TESTING
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 F3340-18 test to provide R-Values for our mats. There are other factors which will determine how well a sleeping mat will insulate; but the standardized ASTM R-Value test means that you can compare resistance to heat loss in sleeping pads across different brands.
THERMOLITE HL-1
Thermolite® HL-1 is part of the family of Thermolite® materials used in Sea to Summit sleeping bags, sleeping bag liners and sleeping mats. HL-1 high loft insulation is a fiberfill constructed with a unique 3D crimp of hollow-core and solid fibers, which provides excellent lightweight warmth with superior durability. The Thermolite insulation lofts up inside the Air Sprung Cells™ of our sleeping mats to prevent convective heat loss from your warm body to the cold ground.
