It's like sleeping on a more durable pool floatie. It's very comfortable. Just blow it up all the way, and then use the quick-release valve to soften it while you're lying on it. Lost one star for noise.

I can't speak to the warmth of this sleeping pad, as I've only used it once, and it only got down to mid-50s. I'll update my review when I get a good 30-degree night's sleep on it.

For reference, this is replacing my 20 year old original Thermarest. That thing kept me warm even when we pitched the tent on 3ft of snow. But this BA pad is more comfortable and packs down very small.

I'm currently hiking the Appalachian Trail. I started with a different pad, but didn't like it because there wasn't as much cushion and my butt would hit the ground when I just sat on it. Before going to sleep I like to sit down and either relax, prepare my stuff for the next day, or just sit and talk. On my previous pad my butt kept sinking into the floor and I was actually sitting on the ground. Someone I met on the trail recommended this one to me, and I bought it.

Cons:
- You might go light-headed while trying to blow it up by mouth. I usually start blowing it up when I set up camp, and come back in about 5 or 10 minutes and finish blowing it up. I was a swimmer in high school and college and like to think that I have pretty good lung capacity, but blowing this thing up all at one time takes it out of you.
- Unless you have the sleeping bag that is made for this and goes inside of it, it can be really noisy. That noise is hard to describe unless you have been in a hiking shelter with someone who keeps rolling around on it throughout the night. (Thankfully I was the noisy one and I slept through it!) Hahaha!

Pros:
- It is super light and super compact.
- Sleeping on this has been so much more comfortable than any other pads I have owned. I'm a side sleeper about 50% of the time and I had no issues with my hip bones or shoulders getting sore.
- While just sitting on the pad, your butt doesn't touch the floor.
- It comes with a patch kit, not that I've ever had to use it, but nice to have.

Overall, I would buy another one.

I can't say enough good things about the my Big Agnes sleeping pad. I love to camp, but one of the things that has been holding me back--no pun intended--is that I get a sore back when I'm sleeping on the ground. I'm just not ready to pull the trigger on a hammock, because A: I feel like I'm presenting myself as a burrito fit for a bear, and B: I feel like if I have to use a hammock, I'm losing something by sleeping off the ground.

This air pad allows me a little bit of comfort without feeling like I'm bringing along a full-blown air mattress.

I like to use it by putting it inside my sleeping bag, so I am less likely to roll off it in the night. It supports me great and easily allows me to let out/add more air to give it the right firmness. I'm a bit of a husky side sleeper, and I toss and turn a lot in the night, but I never felt any hot-spots such as my hips or shoulders touching the ground. The first night I used it, I got my best night sleep in a tent in years.

Finally I'm one of those guys... You know who we are. You may be one of us. I get something that comes in a small package, and once I unpack said package, I can never get that item back in again. When I saw how small the carrying bag was--compared to my previous (roughly) 4x larger (but thinner) sleeping pad--I had visions of hurriedly stuffing this sleeping pad into my pack in the morning and hoping it would fit. To my surprise, I was able to fold it up and then roll it and easily get it back into the bag. T'was wonderful.

Overall I'm thoroughly satisfied with my Big Agnes sleeping pad, and I'd recommend BA's products.

Very nice mattress. I've hiked the appalchian trail twice and these are very comfortable. I've been in 12 degree weather and I didn't feel it through the mattress. I've been in 90 degree weather and I didn't sweat like others were with different mattresses.

I rarely write reviews, but felt compelled to do so on this purchase because I am so happy with it. Took this pad on an overnight backpacking trip last weekend and absolutely loved it. I had to set up my tent on an area with roots and rocks, but I did not feel a thing under this pad. It is incredibly cushy! I also love how small and lightweight it is. After years of using a huge Thermarest pad, I'm impressed with how far technology has come on this ultralight gear. Total game changer. I also think the price is good for what you're getting. Highly recommend.
