Received free productI took the AirRail on some overnight hikes on the east coast. The weight of this pad (1 lb., 14 oz.) is heavier than my Nemo Tensor (1 lb., 6 oz.) or my REI Flash (15 oz.) but since you are getting the sturdiness of a foam pad without the bulk or weight of one, it is a good choice. I love my air pad but admit I live in fear of it busting in some unpatchable way. At least with the AirRail, if you had a leak, you still have a thin foam pad to sleep on.
What I really love about this pad is it is CUDDLY! The rails are a brilliant idea. They really keep you from rolling off and feel snuggly and also protect from drafts. Other good points are the much sturdier valves with large side tabs. On my other pads, I always worry about ripping the valves from the cloth when opening them. The material of the AirRail helps it stay in place better and it is very quiet (unlike air pads). Also, the cloth feels thicker and stronger than an air pad so I would expect it to last much longer. I am a side sleeper who tosses about a lot and I slept very comfortable every time. My Magma quilt worked even better on this pad as opposed to an air mattress.
Why I only gave it four stars is because the “self-inflation” is minimal although it gets better after using it once and fully pumping it up. Took only four pumps to get it inflated with my REI pump bag that I used to use on my Flash. It’s just as insulated as my Nemo (R 4.2) and the bonus was I didn’t need to use my closed-cell foam pad under it like I do on my Nemo.
Bottom line — if 8 ounces more in weight and 6.5 diameter versus 4.5 doesn’t phase you, then I highly recommend this truly hybrid mattress. Sweet Dreams!

Failed After 1.5 years
Fox2 years ago
I thought it would be more durable, just based on the feel of the material. After 1.5 years of careful use, mattress developed an undetectable leak. Then a few weeks later the internal baffles failed, leading to a giant bulge on one side of the inflated mattress. Fortunately this did not occur in the backcountry! So, while I found this product comfortable, I now have to replace it mid-travels. Can’t really see using it as a foam pad on cold ground, as others suggest.

Solid but not for me
2 years ago
The Air Rail Plus is a solid product but doesn't hit the mark for me. It is a self-inflating mattress, but it inflates so slowly (hours) that at first, I didn't think it was actually self-inflating. This isn't a big issue as it inflates quickly by breath or pump. The inflate nozzle fits the hand pump that came with my Exped so this is convenient. The inner foam and thin size make inflating a breeze as compared to an manual inflate air mattress, but this comes at the expense of weight. Pick your poison. The mattress is reasonable comfortable, but with my larger frame (6' 5", 210lbs) it isn't enough. For most people, I expect they will find the mattress comfortable but not cushy. It doesn't have the noise issue that you get with some lighter weight air mattresses.

AirRail Plus Sleeping Pad
2 years ago
I have tried a few other sleeping pads and this is my favorite! Love the design and how easy it is to use. Very comfortable along with my sleeping bag, makes for a good nites sleep. I like that you can inflate to your personal preference. Easy to deflate, roll up and use the velcro strap or put back in its sack.

Quiet and Comfy!
2 years ago
So far so good. It's a comfortable pad that doesn't make noise when laying on it like a lot of other pads - I used it at a small (quiet) concert and didn't worry about shifting around at all. I haven't had a chance to test this in the wild yet, but my last pad was an AirRail - the rails are the best part to keep me from falling off while sleeping! The knozzle broke on my last one but the design on this fixes the issue (see photo). I wish it packed down smaller and I'm worried about getting it to deflate fully when out backpacking. Right now I'm envisioning this for weekend trips or car camping.

not comfortable
1 year ago
I tried this pad out for two nights during a camping trip. As a side sleeper, this mattress pad is too thin and not comfortable. The first night I used it, I could feel my hip bones touching the ground when I slept on my side. The second night I filled it more to compensate for that, but the pad was too firm and felt like I was sleeping on the hard ground. I did not really notice the foam part really aiding with comfort. I also got the regular length and it felt a little short. I am only 5’8” and could feel my feet reaching past the end of the pad when I tried to sleep on my back.

Like sleeping on a cloud! Sucks to put away.
11 months ago
I spend a lot of nights in the field for work and sadly had to replace my REI Flash Sleeping pad after three years (which ironically had really bad reviews but I loved!). I tested this one out last night car camping and holy moly it's very cozy! I was so shocked at how comfortable it is! I really enjoyed it and slept very well. Will be taking it backpacking soon and can update my review then. My only complaint is it's hard to deflate and put away. I could not get it back in it's original bag. I had time to kill so I was trying to but in the field with students I need to pack up super fast so I'm intrigued on how it will go.

No self inflating happening
7 months ago
I don’t see any self inflating happening. Super excited to bring home and test before a big trip where we camp at a different site every night so I wanted it to self inflate. Seems very bizarre because it says that it takes 30 minutes but it’s been like three hours and nothing has happened.

Great matt for side sleepers

I love been outdoors, but camping was hard because I was always achy from sleeping on the ground. I'm a side sleeper and my hips always hurt. This may was fantastic. No hip pain at all.

Side Sleeper Express

After a through testing process of different sleeping pads, I found this one and it works best for me. I’m 6’3” and 250 pounds and I’m a side sleeper. This pad is comfortable and I don’t have to worry about rolling off when swapping sides. The pad supports me as I don’t sink into it and bottom out. Yes, people will say it’s difficult to inflate. My recommendation is to buy a small usb rechargeable hand pump and use that. 30 seconds and boom, the pad is inflated. It is a pain to deflate and roll up, takes about two times to roll up to get enough air out to pack up. But after a few times using it I got it down to a science to roll it up. Overall it is a good sleeping pad. Been using it for a year now and it’s been holding up well.
