I bought this pad for a trip with my son. I was taking this one and a older cheaper version I have. This pad is more compact and lightweight than the one I currently owned. The one feature was how much more durable this one felt, and the fact that over a multiple day trip it never lost any air. An improvement from the previous one. I purchased the large self inflating pad and it was almost big enough for me and my four year old son to sleep on it together. I am a side sleeper.The only negative thing I can say about this product is this one is not intended for a backpacker. This is more for base camping or car camping where weight and size are not an issues. If you are looking for a backpacking pad look at another option.

I purchased the regular sized, rectangular pad. Typically I like a firm bed and just needed something to soften the bones a bit. The first night I slept on this I decided it would e plenty good for someone that values s softer matress. Fortunately, you're able to tune the firmness by topping off the air at the valve. Also, the valve is an excellent design that allows for easy inflation and assisted deflation both.I got this for car camping and it packs down great for my needs. I can imagine it being too bulky for lightweight backpacking though.

Only used this mat a couple times so far. Pillow lock tech is great when combined with sea to summit pillow. It is more affordably priced than comparable mats. Its heavier than many so if ultralight is what one is seeking this mat is not preferred. I am optimistic that the R value makes this a great mat for someone who is backpacking or camping in many conditions and is okay trading off less warmth in winter while carrying little extra weight in summer instead of having multiple sleep mats

Got this mat to replace the standard issue foam ones, but wanted something that doesn't stand out too much, and is tough enough to not be damaged by being used outside with no tent, or people stepping on it in their boots, while also being the same size or smaller as the issued mat.Rolled up without a fold (so longer but narrower than its default bag) it's slightly smaller than the standard issue mats (good although slightly heavier).Definitely a lot warmer and more comfortable!So far seems to be pretty resistant to being walked on (and you can let some air out so it deforms easier) plus it comes with a repair kit (though I wouldn't like to try in the field).Pretty quick to pack up and put away.
We were looking for something to put on top of our cots to make them slightly more comfortable and this is a winner! We were hesitant to buy this because of the lack of reviews but I'm glad we went for it. The instructions say that you need to blow it up the first time you use it and let it sit for a day or two inflated. After that it does self inflate a bit but honestly, I haven't waited for it yet. It's only a few breaths to get it inflated. The inflate/deflate valve works awesome (remove the valve and flip it over to switch modes) so packing up is a breeze. A big foam pad would be more comfortable but the small packed size is really convenient!
I am 6'1" and this sleeping pad fits me perfectly. So far I have used it for both recreational camping and backcountry trips for work. It inflates and deflates easily and the value of comfort in regards to the weight has been a clear positive trade off for me. I recommend this sleeping pad to anyone who isn't looking to spend a ton of money, but wants to be comfortable on the trail.
For a small packed size, this mat packs a punch. When inflated to full, it's very solid but you can also soften it by letting some air out (which is easy to do in small increments). I've now slept on this on a few trips and it absorbs the minor bumps on the ground quite nicely. The coldest night was about -2C temperature and to me this seems to be the lower end of comfortable range for this mat without a space blanket or other insulation (but I do prefer to sleep warm so your mileage may vary).I'm looking forward to many more nice hikes with this one.
Best mat you can imagaine for that price. Materials are outstanding and self inflation sistem is perfect. Only two breaths in and you are ready to sleep on it. Perfect system for storage (reverse valve). Excellent R value. 100% recommend.
Before I bought this particular sleeping pad, I read and watched multiple reviews on which type of mat would be best for me. I choose this mat after having used foam mats in the past that were very bulky and honestly just not that comfortable to lay on. The Camp SI mat really impressed me when it arrived and was in such a compact storage sack. It fit perfectly inside my pack, taking up a quarter of the room a foam mat would. When it comes to unpacking and inflating the mat, it takes less than a minute to set up and use. The valve makes it simple and easy to either allow the mat to self inflate over several minutes, or to blow air into if you are in a hurry to get some rest. It is also extremely easy to deflate and folds right back up into the stuff sack very ... MoreBefore I bought this particular sleeping pad, I read and watched multiple reviews on which type of mat would be best for me.

I would definitely recommend this to anyone who is interested in a lightweight, easy to use product.
