Description
The Comfort Plus XT Insulated Mat is perfect for campers who want a comfortable, insulated pad that packs down small, yet inflates with plenty of room for even the most active sleepers.
Two layers of XT Air-Sprung Cells give you unparalleled support. The lower level can be firm for protection against uneven ground, while the upper section can be fine-tuned to your personal comfort preference. This also means that a functioning sleeping mat is guaranteed, even when one layer is damaged.
The uprated 30D/40D face fabric is quiet and durable, and the lamination technology continues Sea to Summit’s class-leading reliability.

Design Details
Technical Features

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

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.

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 2020 we have used the industry standard ASTM F3340-18 test to provide R-Values for our mats. There are other factors which will determine how well a sleeping mat will insulate; but the standardized ASTM R-Value test means that you can compare resistance to heat loss in sleeping pads across different brands.

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.

Frequently Asked questions
Really comfortable at this thickness?
Yes. Thickness isn't the key factor for sleeping pad comfort – the number of points of suspension is. Our air sprung cell sleeping pads support your body weight with hundreds of individually air-filled springs.
Easy to inflate?
Yes! The supplied stuff sack features an integrated Airstream Pump which will quickly inflate the sleeping pad. This means no dizziness for you, and practically no condensation moisture inside the pad.
Did you know that you can turn the Stuff Sack inside out and have a pump for your Sea to Summit pillow? Try it out!
Noisy when I shift around in my sleep?
Air mats (such as our Air Sprung Cell mats) are in general noisier than mats that have a foam construction (such as our Self-Inflating mats) due to their technical construction. However, the reflective material (Exkin Platinum) and the durable outer material of our Air Sprung Cell mats are both very quiet compared to other mats in this category.
Is the Comfort Plus XT Insulated warm enough for shoulder seasons?
Yes. This insulated air sleeping pad has a tested R-Value of 4.7 – warm enough for year-round camping.
