This Sleeping Mat and Dry Sack Pump Bring Comfort and Warmth to the Outdoors

Leave it to the gear masterminds at Sea To Summit to take sleeping pads to the next level. Their Comfort Plus Insulated Mat combines serious technology and durable design to deliver a great night’s sleep, no matter where you find yourself.


Right out of the box, the sleeping mat was easy to use, lightweight, and packable. The design is all about function and would be totally at home in high winds, freezing snow, or the backyard tree-house. Unpacking and inflating the Comfort Plus mat takes less than a minute and could easily be done with gloves.

The mat is pretty straightforward from the start, but has some nice features to explore. The valve system to inflate and deflate could be new to some. One valve directs to a top layer and another to a lower layer, something I missed my first time checking it out.


I used the Sea To Summit Air Stream Dry Sack Pump to inflate mine to test it out, but I also easily inflated the Comfort Plus mat another time with about 8 full breaths without the help of a pump. But, the moisture in your breath can end up reducing the warmth of your mattress. Click here to learn about the science behind sleeping mats.

The multi-function valves split between inflation, deflation, and a slow-release adjustment button. The two levels of inflation is a nice feature of this sleeping mat. Inflate one side all the way for maximum cushioning, then adjust the top layer to your tastes for body positioning. It seems a tad over the top for roughing it, but the ability to adjust the inflation with the touch of a button is a nice little feature.

Comfort and Temperature

I tested out the tapered version of the Comfort Plus Regular size, and it was a bit small for me. I’m 5’10” and about 170 pounds, and I fit on the pad but without much room to move. I’d recommend the larger size for anyone around my size or larger.

The Air Sprung Cells are individual chambers and help the mat conform to your body. Movement and contours don’t affect the Air Sprung Cells nearby, allowing for more comfortable night’s rest.

The dual layers of sprung air cells have the nice perk of staying inflated even if one side gets punctured. I didn’t test the feature so I can’t be sure of how it performs in that way. This style also looks like it would provide a perfect layer of additional warmth from cold or snow-packed ground. The Thermolite insulation Sea To Summit uses is designed to prevent radiant and convective heat loss.


Deflating the Comfort Plus sleeping mat was a breeze, and folding it up for packing took no time. It’s design allows for a packing size way smaller than your traditional Thermarest-style sleeping pad. It would be perfect for long distance cycling trips and backpacking.

In a bug-out situation, when space is at a premium, this mat fits perfectly. The design is durable, sets up and breaks down quickly, and fits a wide variety of temperatures and environments.
