  • Best pad
Style: Tapered - Regular (72 x 21.5 x 4 inches)
I’ve bought numerous pads, this one seems to be the best

  • Very nice pad.
Style: Rectangular - Regular (72 x 25 x 4 inches)
Amazing 4in thickness for side sleepers and packs down to almost nothing. Best overall comfort to weight and price ratio for similar models. Perfect t 3 season pad.

  • Great for Men (and dogs) too!
Style: Women's Large (72 x 25 x 4 inches)
TL;DR - Ultralight, ultra comfortable, ultra strong! Increased r-value and less weight than the mens. Not annoying like Thermarest. Medium sized dog-proof. Would buy again! I'll have to add photos later but as a 5'9" male who sleeps cold, I appreciated the extra overall width and increased r-value! I am an inverted triangle body shape with pretty wide shoulders and love that the mat stays wide even down towards my hips. Lots of room to roll around on as an active sleeper! It also isn't very crinkly or loud. Definitely not enough to disturb or irritate me in the middle of the night. I think it was also just barely lighter weight than the men's version as well. I will say it does take up most of the floor space in my Copper Spur UL1. But with the 4" of padding I've never had a problem hitting my head or feet on the tent while sleeping. This is hands down the best pad I have ever used! It is also bomb proof as my dog had moved all over it getting comfortable and I have had no issues with holes or punctures! ... show more

  • Need a mat that will stay blown up ALL night? This is your mat!!!
Style: Tapered - Regular (72 x 21.5 x 4 inches)
Took this on a 3 N /4 Day backpacking trip and it rocked ! Stayed blown up! Easy to blow up! I would get the rectangle if you are a side or belly sleeper so you can move more than the mummy version…..just FYI CC

  • Best light weight mat I have used
Style: Rectangular - Regular (72 x 25 x 4 inches)
Very clever design -- you inflate easily by compressing a light weight bag looks like a plastic shopping bag (but much better quality). I sleep very well on this mat and so the money I paid was worth it!

  • Happy Side Sleeper
Style: Tapered - Regular (72 x 21.5 x 4 inches)
I’m 5’9” and 200lbs, and I needed a lightweight backpacking sleep mat that was actually comfortable for my strong lady body. This one checks all the boxes. It’s quick and easy to inflate, lightweight, takes up little space when packed, and comfortable. My only complaint, if I were going to complain, is that it’s a little noisy when you are moving around. Such is life on an air mattress. ... show more

  • Disappointed
Style: Tapered - Large (78 x 25 x 4 inches)
Love the size and the light weight. Love how fast it blows up. A little disappointed in the comfort. It is good, but My big Agnes insulated Q core is more comfortable (I am a side sleeper) but it is also much heavier. Disappointed in the durability. Used it on one, 5 day campout. When I went to use it this year, there is a slow leak somewhere. It was not abused and I am very careful with using my gear. For the price, I expected it to last much longer ... show more

  • So comfortable!
Style: Rectangular - Regular (72 x 25 x 4 inches)
Most comfortable mat I have ever owned and I have used a lot of mats! I inflate till about 85-95% full to get firmness I like. Super comfy and highly recommend. I have only had out in a couple of 4 day trips, so not enough use to accurately rate durability/quality, but so far so good.
