Sea to summit Comfort Plus XT™ Insulated

Our updated Comfort Plus XT™ Insulated Rectangular Air Mat provides a generous 8cm of air cushioned comfort, with a dual-chamber design where each layer can be pressurised independently: inflate the top layer to your personal comfort while maintaining a high-pressure base layer for protection from rough terrain.

 

Our updated Comfort Plus XT™ Insulated Rectangular Air Mat provides a generous 8cm of air cushioned comfort, with a dual-chamber design where each layer can be pressurised independently: inflate the top layer to your personal comfort while maintaining a high-pressure base layer for protection from rough terrain.

Utilising a wider Air Sprung Cell™ dot pitch to create larger pockets of air for eXtra Thickness (XT), this mat combines a lightweight 30/40D Nylon fabric, Exkin Platinum® and THERMOLITE® insulation for increased warmth while minimising weight and packed size.

Wider than our standard Air Mats, the Comfort Plus XT™ offers a little more room to move around and the extra height is perfect for side sleepers as it allows your hips to sink deeper into the mat without touching the ground.
Our Comfort Plus™ Insulated Mats employ dual layer technology with Exkin Platinum® and Thermolite® insulation.
The two layers of high resolution cells can be pressurised independently to provide ultimate flexibility in comfort adjustment. Inflate the top layer to your personal comfort while maintaining a high pressure base layer for protection from rough terrain. Independent chambers allow the mattress to function even if one of the layers is punctured.

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
Dual layer construction uses two independent high resolution layers, giving greater sensitivity by distributing your body weight and shape over more cells. The two layers are offset for more uniform insulation, support and cushioning.
The Comfort Plus range provides the most effective system for fine tuning the level of comfort available in any air mattress today. If you are on eneven or bumpy terrain, the you can inflate the bottom layer of the mattress very firm at higher pressure as a barrier. You can then adjust the upper layer, using the fine tune valve, to a lower pressure to feel softer and more comfortable. The Dual layer design also ensure a level of built in redundancy. If you do end up with a puncture in one layer of the mattress, then you can still get through the night with the other layer of the mattress intact.

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.
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.
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.

Dual Layer construction uses two independent high resolution layers, giving greater sensitivity by distributing your body weight and shape over more cells. The two layers are offset for more uniform insulation and cushioning.
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
