Rated 4 out of 5 by from Comfortable, packable, looks good I used this on a little 2,189 mile walk they call the A.T.. The pad is incredibly light and more comfortable than any mattress I've ever owned. Comes in solid colors. Literally the only reason it's four stars is because the durability does come into question, especially with air pads in general and even more so on a 4 month hike. However, for anyone going out for less than 4 months and wants the most innovative pad made by one of the coolest companies, this is for you. Just sleep with a view, because if you pair it with the Tango Solo sleeping bag and dear lord you'll have a killer UL set up and you'll rarely want to get out of bed.

Rated 5 out of 5 by from Astro Air Lite 25L I have slept on this pad for ten days and am very pleased; the thick three inches and wider size provides comfort. It is light, easy to blow up and holds air. This is my pad of choice for this year's backpacking season; Colorado and Alaska.

Rated 5 out of 5 by from Sleeping Pad for Pacific Crest Trail Thru Hike After having some problems with the Zor 20s I was unbelievably pleased by the durability and comfort of the Air Lite 25. It was far larger than I realized but that really wasn't a problem. It fit beautifully inside the Hornet 1P so that the pad didn't have room to walk around on you in your sleep but had enough space to store a few things inside your tent if you wanted to. I wound up having an extremely tiny pin hole on the very edge near the pillow but it patched perfectly with one of the pre cut yellow circles (which are awesome!) and a dab of the patch adhesive on the bottom side. After that the leak was no more! I only have two complaints. The valves seem to jam up every once and a while with dust or dirt and take some finagling. The second complaint would be the pad takes some lung endurance to blow up. This issue would be solved by getting one of the cosmo series pads with the foot pump, although it is a bit heavier. You win some you lose some. At the end of the day what really matters is how comfortable you are. This pad is wonderfully comfortable!

how noisy is the pad. The Tensor is noisy, how does it compare?

Asked by: jeepstergal
​This pad does make a similar amount of noise as the Tensor.

I recently purchased a long nemo sleeping bag, will this pad fit inside the sleeping bag?

Asked by: Tootalltim
We cannot guarantee compatibility without knowing the exact bag you are trying to fit.

Is there a 'pump bag' to use to inflate this mat? One on the market that is compatible with this air valve on this mat?

Asked by: Walkin Joe

Is the noise, significantly less than Thermarest, which sounds like you are sleeping on a bag of chips?
