Sea to Summit Ultralight Insulated Mat - Large

I chose this after months of research as it seemed to offer the best compromise between all my demands. This replaced my lattice-style Klymit O-zone for backpacking because I switched my sleeping bag for a quilt and needed an insulated pad under me. My practice with backpacking equipment is to get as light as possible without the extent of livability sacrifice often associated with ultralight.There are lighter pads out there for sure, but this one is a couple inches wider than the usual 20" which ups the comfort value for me a lot; it's less noisy than any other air matt that employs heat-reflective insulation (there is no additional noise from the insulation in this one, which was mandatory for me); it is price-comparable if not slightly less expensive, and only ... MoreI chose this after months of research as it seemed to offer the best compromise between all my demands.

My practice with backpacking equipment is to get as light as possible without the extent of livability sacrifice often associated with ultralight.There are lighter pads out there for sure, but this one is a couple inches wider than the usual 20" which ups the comfort value for me a lot; it's less noisy than any other air matt that employs heat-reflective insulation (there is no additional noise from the insulation in this one, which was mandatory for me); it is price-comparable if not slightly less expensive, and only about 1oz heavier than others of similar comfort and insulation value...with a caveat. It's a thin pad, so in order to get the full comfort, this matt really needs to be inflated to maximum firmness in my opinion, which I don't think is possible to do with your lungs because of the flat inflation valve; therefore, the inflation sac / carry bag comes along and that's another 2+ ounces.Inflated to max, I can feel the ground sitting or leaning on it or as I change positions, but not lying on it. I'm 5'5" and around 130-135. I slept well on it once I accepted that I couldn't settle into my normal stomach-sleeping position. Back and side positions feel fine, but the narrowed-out shoulder width on this women's specific pad means that elbows pointing outward from the body or arms spread away from you will be on the bare cold ground. If you are a stomach sleeper who tucks your arms beneath your chest, you'll be fine. For car camping where weight isn't an issue, I'd go for something far more comfortable, but for backpacking I think this is right on point, especially if you value width over thickness. As for warmth, I think this is truly a 3-season pad and look forward to using it on chillier ground.

I now have 2 extra smalls. As far as I can tell, this is the lightest inflatable around: it is certainly a major improvement on any other mat I've owned. The XS is more than long enough: I can't understand why you'd want a longer mat for hiking. Whilst it is thin, these are thick enough to do the job, are ridiculously easy to inflate and very fast to pack up. The yellow colour gets dirty quickly (very small matter), and whilst insulated, these mats are still detectably colder than SI mats. They are moderately slippery and can move around a bit. The noise is HIGHLY over-rated: I don't know how people even notice it! Seven uses, all bush camping (no prepared campsites) and no problems at all so far. I would definitely buy another (I just did! Wifey now has one too). ... MoreI now have 2 extra smalls. As far as I can tell, this is the lightest inflatable around: it is certainly a major improvement on any other mat I've owned.

We are currently using these pads in our hitchhiking round the world tour, they are very comfortable for sleeping and easy to inflate but after 2 years of travel, they start to have many holes in the middle of the "air sprung cells". In the beginning i though the holes came from some kind of thorn and i fixed them with the adhesive patches provided, but the pads kept deflating during the night. This morning i inflated my pad and filled the "inter cells" with water to see if any air bubbles would appear and i just found 5 more holes, always in the 'inter cell" parts of the pad so i am sure the holes are not from thorns but from a default of the fabric. I always find myself on the hard floor in the middle of the night. Unfortunately i cant find the invoice of these ... MoreWe are currently using these pads in our hitchhiking round the world tour, they are very comfortable for sleeping and easy to inflate but after 2 years of travel, they start to have many holes in the middle of the "air sprung cells".

I always find myself on the hard floor in the middle of the night. Unfortunately i cant find the invoice of these two pads and i just ran out of adhesive patches to fix the pad. I would recommand for light weight and comfort but not for durability.Anything SeaToSummit could do to help?
