Sea to Summit UltraLight Insulated Air Sleeping Mat R

The Ultra Light is available in Small, Regular and Large sizes, and with or without 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

Our single layer UltraLight™ Insulated Mats provide the lightest and smallest packed size mat without compromising on comfort.

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!.

The single layer of medium resolution cells provides the lightest and smallest packed size mat without compromising on our 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.

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.

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.

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.

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.
