    • Survived Antarctic Fieldwork
Style: Rectangular - Regular (72 x 25 x 4 inches)
Needed a sleeping pad for fieldwork in Antarctica so I searched for a good insulation rating. This sleeping pad came with a high R rating, super lightweight and was easy to inflate. The carrying bag turns into an inflation device and makes quick work of the job. No more getting light headed manually blowing air to inflate! I used this sleeping for 30 days of tent camping during the Antarctic summer and it held up wonderfully. Highly suggest for those who enjoy winter adventures! ... show more

    • Warm and light
Style: Tapered - Regular (72 x 21.5 x 4 inches)
Extremely easy to inflate with the pump sack and packs away quickly. Kept me perfectly warm down to 20 F, I haven't tested the lowest rated temperature.

    • Very comfortable
Style: Rectangular - Regular (72 x 25 x 4 inches)
Very comfortable at four inches thick,even though not the warmest and lightest like the thermarest Neo air Xtherm. I was hoping they would have the rectangular version with the temperature rating of the women's version temperature rating, which is a tapered sleeping pad, however the temperature rating of this pad is slightly lower. Not a fan of tapered sleeping pads as they are too narrow and I roll off easily. Another thing I dislike about this pad is that, it is very noisy when you are turning on it. I purchased a sea to summit Aeros Ultralight regular pillow and it is punctured and I used the 3m included patch kit for the sleeping bag to patch it and it still keeps deflating, so that was a waste of $40.00 and it was not the most comfortable pillow,as it keeps sliding around and has no back straps to hold it still in place on the pad. The pillow lock feature on the back of the pillow doesn't work well either, so I will be returning it. ... show more

    • Ok but not the best
Style: Tapered - Large (78 x 25 x 4 inches)
Definitely warm, definitely thick, mostly comfortable. Ended up keeping the Nemo Tensor instead. This pad is warmer and thicker but somehow less comfortable than the Nemo. Has a balloon rubbing sound when you roll around, is much heavier, much bulkier and just wasn’t as comfortable to sleep on. I even prefer the old S2S comfort plus to this even though that pad is only 2.5 inches thick. This one just comes off feeling like a thick rubbery plastic ... show more

    • Surprisingly Comfortable
Style: Rectangular - Regular (72 x 25 x 4 inches)
This is a super comfortable mat. It also worked well in the cold (low 40s). Inflating it would invariably take about 5 minutes, and was more of a process than one of the competing mats.

    • Warm!
Style: Tapered - Regular (72 x 21.5 x 4 inches)
Perfect for colder backpacking trips. Nice and sturdy and keeps me much warmer than my old pad. Fills extremely quick with the included bag.

    • Comfortable, but noisy and leaked air
It’s comfortable, but the insulation inside makes a crinkling sound and the pad lost a lot of air and just 24 hours. I am going with a Exped Synmat mat instead, which as held air for over a week now and it’s just as comfy.
