Roland Tyson began making outside gear on an outdated industrial stitching machine in his childhood bed room in 1983, at 17 years outdated. As a younger outside fanatic, Roland realized that he had a ardour and a expertise for creating cutting-edge outside gear. Quickly he was designing and manufacturing gear for different Australian adventurers. By 1991, Sea to Summit was born after outfitting an uncommon first ascent of Mt. Everest (a 1,126+ kilometer, 8,848 meters in elevation trek from sea degree to a solo summit). 

Sea to Summit

At this time Sea to Summit is a multimillion-dollar outside model juggernaut that produces top-quality gear in every part from tents to tenting towels. This previous summer season I used to be invited on a 10-day tenting journey in Glacier Nationwide Park Montana and wished to pack as gentle as doable to keep away from paying for further checked baggage. In my seek for a compact sleeping bag and mat I got here throughout a few of Sea to Summit’s choices and settled on their Ultralight Insulated Air Sleeping Mat for my journey. 

The Ultralight Insulated Air Sleeping Mat or UIASM as I might be referring to it for the rest of this evaluate was independently bought on my own, and Sea to Summit has had no enter on this evaluate. 

Sea to Summit

The UIASM was examined over the course of 5 months on a number of tenting journeys in the summertime months of Montana to the cool autumn months of Maine.

Sea to Summit, Ultralight Insulated Air Sleeping Mat – Consolation  

The UIASM provides a stunning quantity of consolation given its dimension and weight ratio. Coming in at 2 inches thick, there’s a stunning quantity of cushion included with this mat. Sea to Summit packed is their Air Sprung Cell design that delivers stability and assist to your again. The Air Sprung Design along with many dot welds creates small pockets of air all through the mat giving it, its distinctive design. One small draw back I discover with these dots is that they’ll gather filth or sand over time if not shaken out. One benefit to the dot welds is that you just gained’t must fill the mat with as a lot air which means you gained’t get as light-headed late at evening when establishing camp. Whereas as regards to inflation, the Stuff sack that the mat is available in can be a pump sack which means that you would be able to gather air within the sack and easily roll it onto the pad. I discovered this to be a really helpful characteristic and allowed me to fill the mat in a short time. Lastly, the is just not a loud mat however is definitely not fairly both. Personally, I’m a heavy sleeper so this didn’t hassle me a lot however after I would get up it was definitely the loudest individual in my tent at instances.

Sea to Summit, Ultralight Insulated Air Sleeping Mat – Weight and Packability 

As talked about earlier than I selected the UIASM primarily for its dimension and packability as I didn’t have a lot area in my bag for something apart from an ultralight sleeping pad. This mat is available in at 16.9 oz for the common dimension mannequin and could be packed right down to an extremely small 5 x 9.5 in. That is by far the UIASM’s greatest draw and for good cause as its dimension is very aggressive in its market. Most different mats that I personal whereas, not within the “ultralight” class are a minimum of 30% – 40% bigger making them rather more troublesome to pack up. This mat was definitely designed with weight and dimension in thoughts and it reveals all through.

Sea to Summit, Ultralight Insulated Air Sleeping Mat – Heat 

The UIASM mat is marketed as being a 2.5-season mat and coming with an R-Worth of three from Sea to Summit. The R-value for insulation is a method to measure how a lot resistance the insulation has to warmth stream. The upper the R-value, the extra resistance and the higher the fabric is at insulating you from the chilly. Since more often than not when tenting, you can be sleeping on one thing chilly, it’s a good suggestion to have a mat with a good R-Worth. 

Sea to Summit

Whereas summer season days in Montana could be heat, the nights can get very chilly, particularly within the mountains. I discovered the R-value of the UIASM to be good for summer season tenting within the mountains however as soon as I into the autumn, not a lot. I’m an individual who generates quite a lot of warmth naturally and likes to sleep in colder rooms and even I discovered this mat to be not heat sufficient for fall tenting the place the temps get beneath 40 levels Farenheit. I believe it is a nice mat, I simply additionally assume it’s extra of a 2 season mat and never a 2.5 as marketed. 

Sea to Summit, Ultralight Insulated Air Sleeping Mat – Sturdiness 

Sea to Summit

Sturdiness on the UIASM has been nice in my testing. Whereas I’ve not had this mat for a full 12 months, I believe it can final a really very long time. The mat is constructed of 30D / 40D nylon with TPU lamination giving it a light-weight but rugged really feel. The one place I might see a possible sturdiness concern is with the purge valve that you just use to inflate the mat with. I not too long ago had one in all my Sea to Summit tenting pillows with the identical system fail on me after 5 years of use. This isn’t a knock on the mat however reasonably simply one thing to bear in mind. 

Sea to Summit


  • One of many smallest mats you will get in the marketplace
  • First rate consolation is given its dimension and weight
  • Excessive-tech supplies and manufacturing processes result in perceived long-term sturdiness


  • Not very large for bigger campers
  • Supplies are noisy
  • Not as heat as its competitors

Sea to Summit, Ultralight Insulated Air Sleeping Mat – Wrap up 

Total I believe Sea to Summit did precisely what got down to do with this product. The Ultralight Insulated Air Sleeping Mat is extremely light-weight and packable supplying you with the liberty to deliver it on extra adventures. It’s not the warmest mat however that’s additionally not what it was designed for. I’d suggest utilizing it for summer season excursions or when dimension and weight are of the utmost significance. Coming in at $150 MSRP for the common dimension, I believe it additionally strikes an excellent steadiness of worth and efficiency.
