Sea To Summit Comfort Light Insulated Mat - Green, Regular

You get it all with our Comfort Light™ Insulated Mat: comfort, minimal weight, insulation and durability.
When we set out to design a mat that was better than what was already available, we ultimately went back to why we carry a sleeping mat into the wild in the first place — to give us a better night’s sleep. ‘Better’ is of course a very subjective ambition and while we could have made the lightest, or the most compact mat ever designed, we’re stoked to present what we consider to be the most comfortable sleeping mattresses available. Happy sleeping!

Air Sprung Cells - Hybrid Layer
Dual layer construction in the torso for maximum comfort and support, and single layer construction in the head and legs where it’s needed less.
The air sprung cells are the core technology of our Sleeping Mat range, and are the reason why you will sleep better on a Sea to Summit Sleeping Mat. Instead of the typical baffled construction, Sea to Summit sleeping mats are constructed using a dot-weld pattern to create a high surface-area matrix of interconnected chambers called Air Sprung Cells. Air Sprung Cells operate in the same way as a pocket spring mattress, as each cell deforms independently the mattress conforms to your body shape which feels softer and more comfortable with more body contact area and even dispersion of pressure.
Our TPU lamination is applied through a process unique to the medical and aeronautical industries. Extrusion lamination is more durable, consistent and enables us to use our own TPU recipe. It is vastly superior to roll-to-roll lamination, which is used in most other outdoor products at present and can suffer from delamination issues. We have also introduced an anti-microbial treatment into the TPU to prevent mould or fungal growth.
Multi-Function Valve
To make inflation and deflation easier, Sea to Summit has developed our own, patent-pending multi-function valve.
The valve integrates an inflate port with a one-way valve to prevent air loss before you seal the valve, a rapid air dump deflate port, and a fine tune button to adjust for comfort – all in one compact, low profile unit.
PillowLock™ System
Easily secure your Sea to Summit pillow to your Sea to Summit mat for a slip-free sleep.
Designed to keep your pillow exactly where its meant to be—on your sleeping mat—our unique PillowLock™ hook-and-loop fastener patches come standard with all our mats from mid-2019.
R-Value
ASTM F3340-18 R-values An R-value (Resistance-value) is a metric used to rate how effectively your sleeping mat resists heat loss. It’s the only way to know how well your mat will prevent your body heat being leeched away by ground temperatures (which can be a lot colder than air temperatures).
This value can be tested in-house but at Sea to Summit our mats are independently tested at a laboratory to precisely controlled standards.
The new industry standard ASTM F3340-18 testing has now been introduced and all Sea to Summit mats released from 2020 onwards are tested to this standard.
