Thermarest talks about trapping your body heat so, what happens if you camp in 90+degree weather that us humid? Will you sweat against it?

I never slept directly skin on pad. I always covered it with a sheet. I am very heat sensitive (hate it) and never had a problem. When camping, I know you can't be carrying around a sheet with you, but I would assume that if you are wearing lightweight clothing when sleeping that there would be no problem. I cannot say enough good about this product. It got me through nine years of sleeping on the floor while I was caring for my mom and is as new now as it was when I first started using it.

Funny you should ask, I was wondering the same thing.On The One hand I really don't think so, However with me being in the hottest part of of Texas, I don't usually sit outside in the summer time, especially when the temp. reaches 98 or 100.

Last winter I camped for 1 week in the Coronado mountains in Arizona, when temperature dipped to less than 10deg F. I could just manage. So 20deg F should be no problem.

I used it last fall and I do not recall it feeling hot. Overall, I was pleasantly surprised how comfortable it is in our camper.

Yes. We live in the central valley in CA where the temps can hit in the 100's and have found it to be comfortable. Although we are not a humid area. Very dry. So I can't speak for a humid climate. We love ours and would definitely re-purchase.

For myself no, it is not heat trapping. But I have a super thick mattress pad over it. It also depends on your climate.

Yes, with high heat and humidity like here in Houston, Texas you can get overheated in summertime. But, you can get overheated in these conditions humping with just a pack when it's hot out. I've used mine for a year and a half and have nothing but good words for it. I use it as a day pack with long term supplies in main backpack. Note that it does a great job of balancing out your load making it more comfortable to carry heavy loads. What I do when I get overheated is unzip the rib pack and let it hang loose, drink lots of water and rest in the shade a while before continuing. When wearing it by itself, it doesn't contribute much to your core temp. Hope that helps. Yes, with high heat and humidity like here in Houston, Texas you can get overheated in summertime.

If it's hot, the contact with your body is what makes the little one sweat. The cotton never felt uncomfortably warm. We were just at the beach and my LO napped in it while i went for a walk.

I've never experienced sweating while laying on it but if you're worried about it you can use one of those Clorox or Lysol wipes on the plastic spikes or for a more natural approach, you would be fine lightly spritzing the whole thing with a lavender and tea tree mix similar to yoga mat sprays. Just don't saturate it and give it a chance to air dry before storing it again. I doubt you'd need to do this more than once a week, even with every day use.

It was too hot for me. It's not noticeable when you first lay down, but by the morning I started waking up repeatedly from the warmth. I tried to move around but any spot I moved too got too warm after 10 mins.

I'm very hot-natured and hate being hot. We sleep in tshirt PJs with a sheet and a cotton blanket at about 74-75F thermostat setting at night in the summer (78F on thermostat during the day to factor any residual warmth in the mattress), and my back does get warm, but not sweaty. In winter, though, we save $$$ by not needing to run the heater much, if at all, at night (about 68-65F in the house).We're happy enough with the 12 inch mattress and use the warmth to our advantage in winter. We decided on the 12 inch because we measured how far down we sank on our old memory foam mattress. It was a good 8 inches. That fact trumped our questions about heat. hehehe I'm very hot-natured and hate being hot.

YES! My best friend had it. We in live in OK where it's usually over 100 degrees, then humidity is about 3 or 4 degrees at least. She constantly complained about this seat being SO hot for her daughter.

I get really hot when I sleep too and I sweat under this comfort but not as bad as I did when we had a heavier one. Hope this helps.

I play in Southeast Asia in 100 degrees. I have to sometimes leave it off, due mostly to just the overall sweating, never mind with a glove on or off. So, during warmup I'll use it, but then during the game I leave it off and just take whatever impact may come (I play shortstop,so not as bad as say, 1st base). We do get the occasional day at only high 80s & 90s and on those days I'll use it pretty much the whole time.

It does retain heat a bit. Not terrible though if you use good cotton sheets. The comfort is worth it.

It does not say on it. However, I would think you would be extremely miserable out in the heat with this stuff on. It is HOT!!

We used ours in our RV last summer when it was 104 during the day, and the AC was working extra hard. There were no problems with the mattress holding in the heat. This is our 3rd memory foam mattress, and we have never had a problem with the heat. They are just very comfortable!
