Complete The System
The Comfort Plus™ Insulated Sleeping Mat earned its Backpacker Editors' Choice award, 2015 for a combination of its Air Sprung Cell™ technology and dual layer comfort. With two separate layers of interlocking air chambers and our multi-function valve, the sleeper can fine-tune the top layer to perfection, and adjust the base layer to accommodate for rough terrain. The built-in redundancy is not to be taken lightly - if one side of the mat punctures, the other is still able to function until a repair is made. It's insulated with Thermolite® and Exkin Platinum® for great warmth.

Technical Features
Dual 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 Plus series of mats has an internal layer of 40 Denier Nylon dividing the mat into an upper and a lower chamber. This allows the welds of the lower and upper cells to be offset throughout the entire mat, resulting in the greatest possible support and insulation, and a unique ability to fine-tune comfort. When on uneven terrain the bottom layer of the mat can be inflated to a high pressure as a barrier. The upper layer can then be adjusted - using the fine tune valve – for more comfort and softness.
This also ensures a level of built-in redundancy. If one layer becomes punctured, you can still get through the night with the other layer of the mattress intact.
Dual layer construction air mats are perfect for those looking for the ultimate in comfort and insulation, who are prepared to carry a few more ounces
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 F3340-8 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 1, 2020, we are using the new industry standard ASTM F3340-18 test to provide R-Values for our mats.
In some mats, the new test protocol means changes to previously published R-Values. Where values do change, it doesn’t signify a drop or increase in warmth—it simply means they have been tested using a slightly different scale. The packaging may still carry the pre-2020 R-Value.
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.
