When sleeping on my side will my hips and shoulders hit the ground? 5'5 200 lbs

I'm 6'0" and 220 lbs. Yes, for someone our weight, you will compress this pad down to almost nothing at the pressure points of your hips and shoulders when side sleeping. When on your back, with the weight more widely distributed on the pad, the comfort is much better. But the comfort is very dependent on your situation. Are you at 5,000 feet and above treeline sleeping on solid rock? You'll be wishing you brought an air mattress. Are you on the soft floor of a pine forest? Clean out the branches, twigs, small rocks, and pine cones and this will be pretty comfortable. Are you on a sandy desert floor? Again, clean out the bumpy stuff and you should sleep pretty well. Are you in an alpine meadow full of clumpy grasses? It's not gonna be a good night. But, this thing is light, cheap, tough, easy to deploy or pack up, and it has multiple uses as a seat, wind barrier, protection from hail, pack frame, and a place to kneel or put on your boots in the morning. Versatility, durability, and price are the reasons these pads are still around even though inflatable pads offer much more comfort. On the other hand, they are not nearly as comfy as an air mattress, they are ugly outside your pack, and they are bulky. If you can get used to the lack of comfort and you're not going out in sub freezing temps these are probably the best solution on the market. Oh, and they make a great float for relaxing in a pond or stream. Not a life saving device by any means but they'll keep you afloat with your body slightly submerged in the water like a pool chair for some lazing around for a few minutes. Of course an air mattress can do the same thing.

Does this sleep warm in the summer? I’m mostly hiking Florida and need no help in the hot sleeping department.

I just finished a month of military training in Louisiana using this pad. I also sleep warm, and I didn't have any issues with it.

Why are there two different r values? one says 1.7 and one 2.2. the same product at rei said 1.7

Hi Jonathan - There are two versions of the Therm-a-Rest Z Lite Ultralight Foam Camping Pad. There is the "Original" version with a R-Value of 1.7, and the "SOL" version with a R-Value of 2.0. The Z-Lite SOL has a reflective coating on one side (the "Up" side) that reflects body heat back towards the person on the pad and increased the R-Value just a bit with very minimal added weight. - The Therm-A-Rest Customer Service Team

What is the size and weight of this pad?

It weighs about a pound and when stretched it its about 6 feet long.

Un luxe en extérieur

Un comfort incroyable pour une nuit reposante, assez fragile ce qui est dommage. Pour une utilisation intense a proscrire mais pour du bivouac lambda super

Klasse leichte Faltiso

Superleichte, robuste und extrem gut isolierende Faltisomatte. Ich besitze mehrere verschiedene Isomatten welche ich für verschiedene Einsatzzwecke benutze. Voran sei gesagt, diese Matte ist nicht sehr komfortabel. Das ist aber auch der einzige Negativpunkt. Ansonsten ist sie sehr leicht und kann außen am Rucksack transportiert werden ohne dass ein Ungewicht oder eine einseitige Belastung entsteht. Sehr praktisch ist für mich auch die Tatsache, dass sie einfach hingelegt und mitgenommen werden kann ohne aufpusten oder aufpumpen bzw ablassen der Luft. Dies spart viel Zeit, vor allem bei kurzen rasten da so mehr zeit zur Ruhe genutzt werden kann. Außerdem kann die Matte schnell mitgenommen werden wenn es mal schnell gehen muss. Der allerdings größte Vorteil besteht aber in der extrem Isolationsleistung für das Gewicht und der Tatsache dass es nur eine Faltiso ist. Ich habe auf Schnee und Eis mit dieser Matte geschlafen und auf diesem Untergrund auch länger barfuß gestanden ohne zu frieren. Das liegt an der speziellen Oberfläche, die starkt an einen Eierkarton erinnert und durch diese Struktur sehr gut isoliert. Trotz anderer guter Isomatten wie meiner Exped, welche eine Daunenfütterung hat und für arktische Temperaturen ausgelegt ist bleibt diese Therm-a-rest meine Lieblingsmatte da sie so universell ist. Insgesamt ist die Matte eine große Bereicherung und eine klare Kaufempfehlung!
