Static V

I weigh 110kg and sleep great on these. They're way more comfortable than you'd think for how thin they are. They pack down small. They provide some good insulation from the ground. Glad I bought them over a large cbersome air mattress which I could never get a decent sleep on.

Bought this for a 3 week camping & hiking expedition in Costa Rica. Experienced hiker. Opted for the non-insulated version due to its lighter weight and hot climate. Found it super-comfortable compared with various other self-inflating mats used on DofE, but really disappointed that it started slowly deflating after the first week’s use (and almost exactly as the return window closed - grrr!). Could find no visible hole, or hear any air escaping, so unable to put the patch repair kit to any use and spent the rest of the expedition essentially sleeping on the ground. Upon return, we’ve had to submerge it in the bathtub and it took ages to find two minuscule holes on the top surface in the base of the “dips”. So, although not conclusive, we have some doubts about how robust this mattress really is for proper expedition use, having experienced failure fairly quickly after careful use by a female under 60kgs.

Comfortable, quick inflate about the right size, super lightweight-overall excellence to start with. However, we don’t longevity of these is not that great.

Rubbish leaked not much use when you ar eon the side of a mountian

Tested it out when it arrived and it's quick to inflate and comfortable. But finally used it overnight and it leaks, so it's flat by the morning. I've asked for a replacement so hopefully we just had a dud one, and the next one works better.

Incredibly easy to inflate and really comfy for about three hours. Then it deflates. I spent more than I would usually spend on an item like this. I'm really disappointed at its performance. A cheap Chinese one lasted longer than this. I want my money back.

The valve broke after the second time of use. I want a replacement please. It’s only 2 months old

Comparing to other mats I have or have owned it's very comfortable.Better than the Trekology UL80 for me and on par with the Thermarest Neo Air.Very easily to inflate, and despite being thing I found it really comfortable (side sleeping). The major drawback is the value, all the review here and online complain about it. It's just not good at keeping air and I'm not just talking about slowly deflating you can hear the air escaping from it and no amount of fiddling with it makes it better.When plenty of other mats use different and clearly better designs it's baffling why Klymit went with a valve system that struggles so obviously to keep air in. You may find that on 1st usage it's great, after that it just won't hold air. It's clearly a huge design flaw that was never tested properly and it's a real shame as the mat itself is surprisingly excellent.
