Rated 4 out of 5 by from Quality Product Using the Large version (196x63cm with no issues although I am 50lbs lighter than the other 6'5" reviewer. At 660gm it is a decent compromise of cost vs weight vs pack size vs R-value. Fits nicely inside my Rab Ridge Raider hooped bivi. Also fits in the Thermarest seat-adaptor to make an agreeable chair. An inflatable such as a Neo-air or an Exped Ultralite would be lighter, pack smaller, and insulate a little better but you're shafted if they puncture and they need more inflating that a couple of puffs through the valve. Also at 7-9cm depth they aren't always first choice for bivvying as sleeping bag loft may be compromised.

Rated 4 out of 5 by from The best of most worlds The Prolite is almost exactly what every other mattress tries to be. The neoair revolution (also inflatables from Big agnes, Exped, Nemo, Etc) has given us a bunch of mattresses that are less durable, more annoying to inflate, MARGINALLY lighter, and not necessarily warmer than this pad. I've used it by itself in March just off of Mt. Washington, NH, and it was fine, despite having an r-value of 2. If it's cold, pair it with a short z-lite, and you're golden. It weights little more than the really expensive, fragile inflatables, too. Also: tough as nails.

Rated 4 out of 5 by from Finally a pad that's worth it! I'm that guy who has always refused to invest in a nice sleeping pad. I've never thought that the added comfort was worth the money, space, and weight. In the past, I've only packed in one of the cheap blue foam mats if I knew temperatures were going to drop pretty low. Well, my last trip was going to be pretty chilly and I found a good deal on the Pro-lite small. It packs down tiny and added way more comfort than I was expecting. I found a way to strap it to the outside of my pack so it took up no extra room. I've been converted.

Rated 2 out of 5 by from Does not self inflate. I've had a few ThermaRest pads before, so I know what to expect. I've taken this thing on about five backpacking trips so far. It simply does not self inflate. Just in case you're wondering: yes, I store it rolled out and not packed. This thing just doesn't self inflate. Rolling it up was a pain in the butt and it takes up quite a bit more space than the original packaging promised. I noticed that the previous person who complained about this pad not self inflating got a lot of 'thumbs down', but I can completely concur and had the exact same experience. I've had about four self inflating pads in the past -- this is the first that simply DOES NOT self inflate under any circumstances.

Rated 5 out of 5 by from pretty comfortable over the z-lite Bought this as an upgrade from my z-lite so I can save space in my pack. Pad inflates enough but for me I had to top it off firm. I wish I could say I'm a side sleeper. Or a belly sleeper. Or on my back. I actually turn so much I wrap and tangle myself in my bag. But I found that no matter where I was in my turn at night I was pretty comfortable on the ground. First night the pad kinda deflated but not completely. I attribute that to not closing the valve all the way because my second night it stayed full all night. I like how I can pack it in and takes up just a little bit of room. Maybe the size of a nalgene maybe?? I will put it to more use this summer but so far, 5*.

Rated 5 out of 5 by from With realistic expectations, you will love it. First, allow me to offer a little general info on pads for the inexperienced buyer. In reading reviews of this pad, or other light weight "self inflating" pads I believe people have unrealistic ideas of what self inflating means. This is the ninth Thermarest product I own, with eight of them being self inflating. If you think self inflating means that any of these will inflate to full sleeping on it firmness in a couple of minutes, you will be disappointed by any of them. All self inflating pads take time to inflate, and they all should be stored fully inflated. They will not self inflate with a sleeping bag laying on top of them. I have never had to patch any of my Thermarest products and I still have my original first generation rust orange model with the metal valve. I have used these backpacking, car camping, canoe tripping, and for 12 years in mountain rescue. Never had even one pin hole. But you can't carry them through a cactus patch on the outside of your pack. This pad is the excellent quality I have come to expect in every Thermarest product. It inflates to about 90% of full on it's own in about 10 minutes. A couple of long deep bloes in to the valve finish it off. It weighs 1 lb 0.5 oz with it's inclued stuff sack, and rolls up compact enough to fit in a pack side pocket. Th eonly negative is how slippery both surfaces are so it tends to slide around on a tent floor or ground sheet.

Rated 5 out of 5 by from Perfect match of durability/comfort/weight savings I purchased this same model some years back and have used it heavily. I've been evaluating my pack recently to see if I can trim some weight and after all these years the Prolite 3 still makes the cut even though there are lighter alternatives. It's a solid piece of gear and I can attest to it's durability having bought it to thru hike the PCT in 2010. I used this pad nearly every night for 5 months and NEVER sprung a leak. Matter of fact I have never repaired this pad! Fluke you say; my wife has the Prolite Plus and we've been hiking side by side with these pads since the PCT, no repairs needed to date. The comfort is plush (i don't care for foam pads) and the insulation has never left me wanting. Also, both of ours self inflate just fine. We do store them uncompressed, valve open. Pad works great for back, side or stomach sleeping. The only downside I can see is packed size when compared to pads like the Neoair but honestly it's a non issue for me. Plus when you consider things like the crackle factor of the Neoair pads and how they seem narrower because of how the edges collapse when laying too far to one side (not great for spooning), its worth the extra space. I've used this pad everywhere from Virgin Islands National Park to the Smokies, the Rockies, Utah and Arizona deserts, the entire Sierra Nevada and Cascade ranges and will be taking it with the me to the San Juans in southern Colorado this summer. Not once have I been disappointed.

Rated 5 out of 5 by from I'm a convert; best backpacking pad out there. When I started backpacking, I was an ultra-light type of hiker. I got a Therm-a-Rest air pad that rolled up really small and was about half the weight of this pad, and my boyfriend got this pad and I laughed at him. I didn't even think it was that comfortable when I tried it in the store. But sharing a tent for three years and having the two pads side-by-side made me realize this pad was a lot more comfortable than my air pad. Despite the thin profile of this pad, the foam helps tremendously with comfort, and it doesn't "bow" under the heavier parts of your body; air pads always seem to end up with a ton of air under your legs but not enough under your body. But hands down, the biggest benefit this pad has over mine is better usability. It has a grippy coating on the bottom so it doesn't slide around on the tent floor, and it doesn't make a ton of noise when you change positions. This makes for a way better sleeping experience. You wouldn't think those details would matter that much, but let me tell you, they do. It's really very annoying to deal with your pad sliding around when you're trying to sleep. And I'm lucky my tent-mate slept so well on his ProLite, because I've been told that the sound of my shifting on my air pad could be heard from other tents in the vicinity. And of course, I could hear it loud and clear as well. After a lot of time in the field, I've conceded defeat. While browsing the REI outlet to find something to spend my 20% off membership reward on, I saw last year's version of this pad, and I caved and bought myself one. Saving $40 on it doesn't quite make me forget the fact that I wasted my money on my last pad, but it helps. By the way, storing it inflated is an absolute necessity. If you crush the foam down by storing it rolled up, you'll sacrifice comfort and it won't self-inflate. Store it in the laundry room between the dryer and the wall, under the bed, behind the coats in your closet... just make sure it's inflated. Happy camping!

Questions & Answers

Hi - I'm 5'2" petite female. May seem obvious - but what size would you recommend I buy? Thanks!

Asked by: kelmel58
This may be a little late as it has been four months since your question was posted, however the regular size will work if you want your entire body to me protected from the ground. If you were to purchase the small, a foot of your body would not be covered. but dependding on your trip or use for the pad the small can work. Hope it all works out.

I'm 6 foot tall, 210 pounds...which size would be best?

Asked by: kickball jesus
This really depends on how active you are when you sleep. If you just lie on your back like a mummy or my wife, you'll have no trouble fitting on the regular, but if you move around much at all, you'll be much more comfortable on a large. That being said, I am 6 ft 220 lb and I use a small with my sit pad and pack under my feet. Used with a quilt it's quite comfortable, and it deflates and rolls much more easily.

The small is only 3ft 11in, is that correct?

Asked by: JennFlem
Yes, this size is used by someone who wants to cut every ounce from their pack weight. For most people, your body would be on the pad and your legs unsupported. This size also work for kids.

How long does it typically take to inflate the first time unrolled after purchase?

Asked by: NewCamper
When unpacking a self-inflating sleeping pad for the first time we recommend giving the pad at least 24 hours to inflate on its own, and then add few puffs of air into it to bring it to full volume.
