The Comfort Plus Insulated mat carries a thoughtful, durable design that focuses on delivering the plushest night's sleep. If you're not focused on ultralight backpacking and looking for the most comfortable, three-season sleeping mat, this is the perfect choice.


  • Incredibly comfortable
  • Ease of inflation, deflation, fine-tuning
  • Durable


  • Heavy
  • Bulky
  • Not ideal for ultralight backpacking

Ease of Use: Most inflatable sleeping mats are not difficult to use, but this sleeping mat contains inflation valves that are highly intuitive. It doesn't take much time to fill, and the nifty deflation valves release all the air in a second or two! Easy to roll up and store in the provided stuff sack.

Features: The dual chamber valves allow you to fine-tune the firmness of the mat (my preference: 10-11 breaths into the bottom chamber, 5-7 into the top chamber). If you over-inflate a side and wish to let out a little air, firmly press the orange button you see inside the inflation valve! I've tested around 20 different sleeping mats and none come close to the feeling of a real bed like the Comfort Plus Insulated does. Comes with a patch kit!

Construction & Durability: 40-D Ripstop Nylon not only makes this mat feel durable, but lives up to its quality. I've solo camped in semi-rocky/rooty floors for over a year with it and am seeing no signs of wear. Construction is top-notch; price matches what you're getting.

Conditions: I've used this mat from backpacking and camping in 23 degree, snowy weather in a tent to a utilizing it as a last resort bed in a friend's living room. Amazing, warm, and comfortable all around.

Nice review, John! Thanks for taking the time to share it. I'd love to see some pictures of your S2S mat in your review, if you're willing to share some.

Like a Beautyrest.


  • Warm
  • Comfy
  • The pump!


  • Heavy

I got this one because I need a good night sleep or I morph into a Hulk abomination.  

It can be inflated by mouth, but it also has its own pump and that was what I was after. With the pump, both sides inflate under a minute. One side is firmer, one side is softer, the pad is way quieter than my old crinkly Thermarest.  

It is on the heavier side, so keep that in mind when figuring out your full pack weight, but for me it's well worth it.

I bet the Hulk abomination doesn't worry about pack weight! ;) Thanks for the review, Lilia.

I used to have two Therm-a-Rest self inflating mats (1980) and was never happy. This StS insulated mat is a lot better on warmth and comfort 10-fold. With my Katabatic Flex 22 top quilt I'll sleep like a king.


  • Very comfortable (I'm not that heavy)
  • Double inflation
  • Quick inflate and deflate


  • A little on the small side in width (regular size)

Very happy with it. Although length is sufficient, I wish there was an option for a little bit more width.

I have the Sea to Summit Comfort Plus Insulated Mat. I have used it on two AT section hikes. Overall I like it, but...


  • Well made
  • Good R value
  • Not too heavy
  • Double sided adds a little redundancy in the event of a puncture
  • Inflates quickly


  • Your hips will sometimes touch the ground when moving
  • Noisy when you move

I have the insulated mat regular size in rectangle. Of the two sections I hikes I did with this mat the first was in the early spring we hiked from NOC to Fontana Dam. It got really rather cold at night and the pad did very well. I was still cold and did not have a great night sleep, but it would have sooo much worse without that pad.

It inflates quickly and the double-sided eggshell is a really good innovation as it adds a little redundancy in the event of a puncture. As for comfort, it's okay. Your hips will sometimes touch the ground, mostly when you move. I'm 6'2 and 207 lbs.

That brings me to my only real complaint and that is that it's loud when you move. When you roll over everyone within 10 feet will hear it. The other section I used it on was Springer to Neels Gap in the middle of summer. Same issue with the noise, in the morning my buddy commented on it. His tent was about 8 feet away. It was also way too hot for an insulated mat, not the mat's fault, but it's something to consider if you're looking to buy one.

I'm not sure if there are quieter inflatable pads as this is the only inflatable one I've ever used. I''m currently looking for a summer pad. I may get another one with a lower R value and wider as I'm a big guy that moves around a lot, but I'm not sure. I'm a light sleeper and the noise gets old fast.
