Fantastic Sleeping Pad!!!

[This review was collected as part of a promotion.] What a bargain. . . warm (R-Value of 7. 4), quiet, comfortable, well made, durable, and relatively light considering it's R Value. I highly recommend this pad for cold nights/conditions. Be sure to maximize its loft for best comfort and warmth. . . the air bag/stuff sack works great to blowing it up. Bravo Sea to Summit!!!

Great Pad

[This review was collected as part of a promotion.] I bought this pad for a camping/hunting trip in Colorado where the temp could get down to freezing. I was very comfortable although it was only down to low 40s. I'm a side sleeper and this was a good pad. Inflated it fully and then let out small amounts of air until it had the perfect amount of give. I got the wide rectangular one. I'm happy with this as part of my system, which includes a S2S Spark Pro 15 bag. I'm looking forward to some more fun nights out this fall.

Loudest Sleeping Pad

I bought this sleeping pad as i wanted to be able to sleep comfortably in much colder temps than my old thermarest that i bought ten years ago was capable of handling. I can get mostly comfortable with it, size and warmth is phenomenal. on the downside though. This is the LOUDEST sleeping pad i have ever used. Every tiny movement or adjustment in the middle of the night and this pad made noise so loud my neighbours at another site could it hear it. Warmth means nothing if the smallest movement wakes you up. used it twice now in 30 degree f temps and 80 degree f temps both having the same problem, both leading me to have no sleep. I cant return it, but its basically going to collect dust as i cant use this unless i can find a miracle to get rid of the sound.

Worked like a charm

[This review was collected as part of a promotion.] I bought the ether light xr pro mat and the ember quilt rated for 30 degrees and i was warm all night. I was in a wall tent (outside temp 30-40 Fahrenheit) It was on a cot and I did have a base layer and non insulated hunting pants and long sleeve shirt, but i left it set up for the whole week and it didn't lose air, and even tho it was cold getting in, I instantly warmed up. I also tried to sleep only in my base layer no socks, and it was perfectly fine. Slept on my side and back different nights. Worked like a charm.

Buy it, but leave the stuff sack home

[This review was collected as part of a promotion.] Excellent pad, great warmth to weight ratio, and packs small for its loft. The only issue not making it a 5 star is the stuff sack/blow-up bag. It is very awkward and difficult to use compared to the gold standard (rhymes with noozzle). This inflation bag doesn't inflate easily, and is too small in circumference for the needed amount of air. It takes 5 full bags to inflate the mat as compared to 3 of the "other" bag. I would buy this pad and leave the stuff sack/ inflator bag at home

Cushy and Convenient

[This review was collected as part of a promotion.] This sleeping pad is easy and quick to inflate with the integrated pump sack. It only takes about 3 full pumps to full inflate. The valve caps are simple and easy to pop on and the inflate valve is easy to use for adjusting the pad pressure. The stuff sack is big enough to fit the pad back in if you roll it up with the original folds it was packed in. So far the only issue is having enough room to inflate the entire pump sack in a cramped tent.

Excellent pad and pillow lock is a game changer

[This review was collected as part of a promotion.] I recently used the pad for a 10 day backcountry trip with temperature ranges of 30-55 degrees. First pad I've used with a pump sack, and now I'll never use a pad without one; extremely easy to use and quick to inflate the mat. I slept very warm with the pad so the insulation seems to be on point. However, I'm 5'9" with about a 42/44" chest. My arms hang off the side of the pad unless I'm zipped completely in my sleeping bag, then they're kind of held up in place. If you're my size or larger I would get the large/rectangular for a little more room on the sides when you are on your back. A very surprising feature was the pillow lock. I used the pad the first few nights without the lock and was constantly shifting and moving my pillow. When i added the lock strips and got my sea to summit pillow locked in, I slept so much better without having to constantly re-adjust the pillow....don't overlook that feature!

Cut the pump sack from the integrated stuff sack.

The STS XR Pro is a 5-star pad paired with a 2 star pumpsack. I have been using a Thermarest NeoAir XLite pad since 2017. When I purchased myThermarest, I wanted a warm pad that was wider than 20 inches. In February 2017, a 25" Thermarest NeoAir XLite pad was only available in the Large size with 77 inch length. I am just under 5'6". The Thermarest has been a very reliable and warm pad for me. But every time I roll it out in my tent, I wish it was a foot shorter. Not ready to go to a 20 inch wide pad, I bought a small STS XR Pro last Novermber. Both pads are Mummy shaped. I finally was able to try my new STS XR Pro pad in Indiana last week. Our first night was just below 40 degrees. The ground was likely good and chilled after 2 months of winter weather. I was very comfortable and not at all cold. I do think it is a quieter pad than my Thermarest and I was fine with about 3 inch less width. I loved the length. Now I have room for my pack at the foot of my pad. Even though the STS XR Pro is a smaller pad than my Thermarest, it does weigh almost 2 oz more. For that 2 oz I got an even warmer and quieter pad, although I wasn't bothered by the noise of my TR. I had read the reviews about the pumpsack, and my friend had told me she didn't like it, but I didn't think it could be that bad. I had made a pump sack for my Thermarest using a garbage bag and a garden hose fitting. It worked quite well, so I was used to using a sack to inflate my pad. But the STS pumpsack requires you to blow into it, not just unfurl the bag and fluff it out with your hands. The first, and only time, I used the STS pumpsack prior to taking it out for an overnight, I had the pad on my bed and I was standing to use the pump sack. It wasn't too bad to blow into the sack with your mouth about 5 inches from the opening while standing. But try that in a tent! The length of the pump sack is over 30 inches. I found it very awkward and inefficient to get it extended to puff air into it. After a hard day of hiking, I don't want to blow with enough force to expand a pumpsack. Due to the top part of the pumpsack being attached to the smaller diameter stuff sack portion of the dual purpose bag, I could not simply inflate the pumpsack by opening it up and unfurling with my hands like I can with my garbage bag pumpsack I made for my Thermarest. This morning, I simply cut the STS pumpsack away from the integrated stuff sack. It works very well, with no breathing required to expand the pumpsack with air. I am looking forward to my second trip with the STS pad and using the shortened STS pumpsack with a much wider opening to inflate it without blowing big puffs of air.

SIDE SLEEPERS!!

Loved this sleeping pad so much, after the first night... If you are a side sleeper, DO NOT FILL IT UP ALL THE WAY. The first night I should have let some air out, but I thought I had aired it up with enough time for the fabric to do it's stretchy thing that always* happens. Except, this mattress doesn't do the stretchy thing. It holds air, so... first night. When you think you need to blow it up all the way and it will deflate some before bed. Do yourself a favor don't make the same assumption I made. With that being said, by the next night it had deflated enough on its own to be perfect. Third night, I did not add or remove air, and it was again perfect. I did not wake up to the cold bitting through my sleeping bag like I have with past air pads. I did have some noisy neighbors so it's hard to say if I ever woke myself up with moving around because their 3 am antics were loud enough to overpower any sounds I may have been making. One morning I was up before anyone else, and it seemed quiet enough to me in those early morning hours to say it's a fairly quiet mattress. I purchased and returned I think 3 mattress pads before this one because they were either too narrow, or not good for side sleeping no matter how much air I put in or took out. I would definitely recommend this air mattress for side sleepers. Given how many pads I went through before landing on this one. The only con I really came up with is the size... it is insulated so obviously going to be bigger and heavier than non-insulated. But this means I can get away without having to bring a blanket to go between me and the sleeping bag. In terms of weight, by removing the blanket I'm still carrying less weight when adding the air mattress. Even with the advancement of technology. It's impossible to find a product that is going to fit everyone's needs 100%. If you are a side sleeper and camping in colder conditions. For me, the pros outweigh the cons (size/weight).

Checks all the boxes

Normally a Hammock camper but in Winter four walls around me is best. That said I've tried other pads out there and found that my shoulders and back hurt by morning and made for a fitfull nights sleep. Purchased the Ether light Pro based on its thickness and good reviews. Because I sleep cold I had a 1/4 inch foam pad underneath and a 1/4 inch foam pad on top. Overnight temps were in the teens. Slept very well with no shoulder or back pain. Warmth was great as well. Love the feature where the S to S pillow locks onto the top of the pad so that promotes restful sleep. Did not use the storage sack as once rolled up It would not fit back in. A typical problem with a lot of backpacking gear. Sent an email to the company and they in turn sent me out a much larger sack that fits the pad much better. I use the flex tail inflator and that worked best. Size is regular wide which has a slight taper and fits me well. Hope this helps.
