Before I dive into the rest of the review and the details, a quick foreword is that from the pricing and the advertised feature, I consider this sleeping pad a premium product. This is not a $20 one time pad from your local discount store. For such a product, I do expect all things to be thought through and considered. I also expect a superb quality.It this pad a good value for a premium product? Definitely NO. There are number of areas where it falls short. Is this a bad sleeping pad? Also absolutely no. It has a number of features that seems to have been done right and a number of features that really lack in thought and execution. Let's dive into the details:Pros:- The sleeping pad is quite comfortable when fully inflated.- I did 72 hr test to see how well it holds air (inflate to taught and wait 72 hrs to see if it holds air). The pad did deflate some, but not much and was still very much sleepable on after 72 hrs. I consider this a pass. Honestly, not a big deal to add a bit more air to it every now and again- While I can't gauge the R value, it does subjectively seems to hold heat better than a regular old-school T-Rest pad and even a fully fledged air mattress. The main part of it has some kind of reflective coating with some kind fabric manifold that seems to be designed to keep things more insulated. The pad is warm, but I can't quite tell if it's R5.6 or R4.3, for example.- Great for backpacking - it folds extremely small (see pic) for easy fit into tight spaces. I can equally see it being used for car camping or sleepovers, however.Cons:- The inflation bag (sack) is a joke. This sack also doubles as a carrying bag for the pad, which is nice touch, but really this is kind of standard for this type of sleeping pads. I spent 5 minutes trying to pump up the pad with it with absolutely 0 progress. Turns out there are several problems with it (this is what I meant by lack of thought here): 1. While the fabric on the main pad is air proof, the seams are not sealed, so the air just escapes through them when you squeeze the sack. 2. Even a bigger issue is that the spout from the main sack to the air inflation port on the pad is not air proof, so basically all air goes out there and 3. The aforementioned spout also tends to twist and cinch, so it's pretty had to position the sack correctly while also squeezing it. Basically consider this bag/sack as non-exist. Either bring a pump (not included) or just use your lungs. With a small lightweight pump and my own lungs for top off, it took about 1 minutes to pump up the pad.2. The pad weighs 760g as opposed to 645g advertised. This is negligible for car camping but for backpacking extended distances & many nights that 100+ g difference starts to add up. Not to mention that this is just false advertisement.In conclusion, the pad itself is good. The inflation sack is trash. Not good for anything but storing the pad in. Is this good for a premium pad? In my opinion: No. Would I get it on some serious sale? Yes.
