Rated 2 out of 5 by from Deflates Just as Fast as it Inflates I was sold on this when I was in the store looking to get my wife and I some pads for a week long camping trip. We were going to be at a different camp site each night so having a quick way to inflate these sounded perfect. The problem is they do not stay inflated. We had two of these and one stayed inflated the whole night the first night. After that, they both were flat a few hours into sleeping. They are also very, very noisy. It sounds like you are rolling around on a bunch of newspaper. I would be OK with the noise if they stayed inflated. For this price, they should be better quality. I returned both of them after the trip.

Rated 2 out of 5 by from Disappointing I bought this because some of the pros recommended it. Well, either they were perfect sleepers in a corpse like position, or they were just paid to recommend the product. Like others are saying, it's stupid noisey. Like laying on newspaper while a clown rubs 2 balloons together in your ear. Also, even on perfectly level ground, I slid off this pad when I moved. My sleeping bag (REI IGNIO) vs this pad, made for a situation similar to a KY Jelly wrestling match. The plus side is that it is super compact, lite, and prevents the cold from coming up off the ground. I'll be returning this after 4 nights of terrible sleep.

Rated 4 out of 5 by from NeoAir Xlite SV I returned my last NeoAir because it was too noisy. I'll return this one for the same reason. Though they are the most comfortable pads I've ever tried, they're just too noisy. I think this model might be noisier than the last. It has the same potato chip bag crunch but also some added metallic crunching noise. I got a large and it took over 15 breaths into the speed valve for it to blow up about halfway. I finished the pad off by blowing into the regular valve. Great pads by all means but just too noisy for me. I'd rather have the previous model without the speed valve and cut some of the weight. Rectangular shape is nice though.

Rated 5 out of 5 by from Take the time to learn how to use this properly My first night with this pad I didn't follow the instructions correctly to closes the valve with 7 folds and i ended up with my butt on the floor half way through the night. I took the time to watch a short video on how to properly inflate and seal it and have had absolutely no issues since. I am averaging 5-7 breathes and have taken this out nearly a dozen times now. The key is to have a good amount of distance between your mouth and the opening when you are trying to inflate it. I have another friend who has the large size and was complaining how long it took him to blow up until I showed him the correct way and he inflates it in 7 or 8 breaths now. I find that this pad has less of the crinkling sound than the last model and the extra 4 oz to be packed up before my friends are done deflating their pads is totally worth it to me at this point. I have owned many pads in the neo air line and this is by far the most comfortable I have owned. Very pleased with this piece of gear!!

Rated 5 out of 5 by from Convenience Easily Outweighs added Ounces I've been using a standard inflatable Thermarest valve for the past five years or so, and this speed valve setup is an astonishing improvement. The speed of inflation and deflation is well worth the added cost and weight. I can inflate this thing in less than ten seconds with just three breaths, but it takes a bit of practice to get there. When I was first starting out it didn't seem like it was any more convenient or any quicker than just using the standard valve. Deflating it is even faster. It isn't very loud or crinkly

Rated 2 out of 5 by from Light and packable but leaks slowly Leaked out the first night. Thought I did something wrong in closing the dump valve. Used it on a long trip with 10 plus nights of use and it leaked slowly nearly every night. I normally wake around 2am anyway so I just refilled it. Bit of a hassle. I plan to find the leak in a bathtub out of curiosity. I may return it. Bummer since I really need something light and small. Also these pads are also very noisy which I did not find a big problem but it might keep another tent mate awake.

Rated 2 out of 5 by from Disappointing. Pad loses air I am actually laying on this pad as I write this review from Mt Laguna on the pct. Three out of the last four nights the pad has deflated in the middle of the night. You really have to make sure you've properly shut the speed valve and even then it loses some air. Further, the speed valve won't blow the pad up fully. You'll have to blow through the regular valve as well. However if you can get this pad to stay inflated, it's comfortable and warm.

Rated 3 out of 5 by from Easier to inflate but... The large opening you blow into to inflate the mattress does work but not quite as well as I expected. It is still better than only using the valve but you must still blow a few breaths through the valve in order to fully inflate this model. The black lining that keeps the air from flowing out of the large opening bulges together and keeps you from blowing more air in. It takes some getting used to but does work for the most part.

Which thermarest sheet would best fit the XLite SV?

Asked by: toddyballgame
At the moment, Therm-a-Rest does not have a fitted sheet that will be compatible with the NeoAir Xlite SV Sleeping Pad.
