When Sea to Summit set out to design a mat that was better than what was already available, they 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 Sea to Summit could have made the lightest, or the most compact mat ever designed, they're stoked to present what they consider to be the most comfortable sleeping mattresses available. Happy sleeping!

The single layer of medium resolution cells provides the lightest and smallest packed size mat without compromising on their Air Sprung Cell™ comfort.




* Air Sprung Cells™ conform to your body shape, providing a more even dispersion of pressure across the mattress for a more comfortable nights sleep
* Multi-function high flow-rate valve provides fast inflate, deflate and easy fine-tuning for personalised comfort
* Ultra-Fresh® anti-microbial treatment to the TPU formula to prevent internal mould growth
* Includes an Airstream™ Pump that is integrated into the stuff sack for quick and easy inflation
* Includes a repair kit for easy puncture repair in the field
* Included Pillow Lock™ system attaches Sea to Summit pillows to mat

Exkin Platinum® and Thermolite® insulation

* Exkin Platinum® is a very lightweight and quiet metallised fabric. Exkin Platinum® thermal technology reflects radiant heat back to the user
* THERMOLITE® insulation lofts up inside the Air Sprung Cells™ to prevent convective heat loss from your warm body to the cold ground
* Extrusion TPU lamination is vastly superior to roll-to-roll lamination, helping to prevent delamination
* Lightweight, quiet and grippy 30/40D Nylon fabric
* Mat: 100% nylon; Valve 100% TPU; Insulation: 100% polyester; Stuff Sack: 100% nylon


Air Sprung Cells - Single Layer

* Constructed using a single layer of medium resolution cells to give you the lightest smallest pack-volume mattress without compromising on comfort

* Constructed using a dot-weld pattern to create a high surface-area matrix of interconnected chambers called Air Sprung Cells, instead of the typical baffled construction, these cells are the reason why you will sleep better on a Sea to Summit Sleeping Mat

* 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


Extrusion TPU Lamination

* TPU Extrusion lamination is more durable, consistent and enables Sea to Summit to use their own TPU recipe 

* Vastly superior to roll-to-roll lamination, which is used in most other outdoor products at present and can suffer from delamination issues

* Features anti-microbial treatment into the TPU to prevent mould or fungal growth


Multi-Function Valve

* Patent-pending valve integrates an inflate port with a one-way valve to prevent air loss before you seal the valve

* Rapid air dump deflate port,

* Fine tune button to adjust for comfort


Pillowlock System

* Designed to keep your pillow exactly where its meant to be—on your sleeping mat

* PillowLock™ hook-and-loop fastener patches adhere to both mat and pillow


R-Value: 4

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.
