"is water proof ... it’s going to last me much MUCH longer than a 20-30$ foam mattress topper will, because it’s meant to go outside and be exposed to the elements."
"I've had a sea & summit dual-chamber pad for 8 years or so, never had a leak ... We live in CO and go camping 8-10x a year, for 3 or 4 day weekends each time."

"Love my S to S pad also. ... Rivals my Select Comfort bed at home. ... Bought a back up in case they go out of business."
"It is easily the most comfortable pad I’ve ever used for side sleeping."
"It ’s one of the best tradeoffs between actual confort at foam 3 inches thick and weight"

"used for the first time at 1 degree and I was nicely warm. ... very impressed with the quality and warmth."
"It’s rated at an R4, while a foam pad like you’re describing is only rated R2."
"I’ve had both the women’s version and the men’s and the women’s seemed to have denser foam, therefore a bit heavier for its size and warmer."

"It is a dual-chamber sleeping pad, so you can tune the bottom chamber to provide protection from the ground and top chamber to give you the right level of cushion. ... None of the other pads on the market can do this, including celebrated Therm-a-Rest and Exped offerings."
"The dual air chambers prevent you from bottoming out when side sleeping"
"and redundancy"

"My wife has S2S mattress - the one you are looking at or slightly colder and she likes to sleep warm. ... too close to the ground and it'll get cold in the middle of the night."
"Sea to summit are also comfortable but don’t insulate as well."

"Or if it's little seam weld pinholes, take advantage of the warranty (I use Sea 2 Summit pads mostly). ... but i'm not really talking about those kind of holes (that can be patched) - i mean the phantom leaks that can't be identified or fixed easily, like seam welds, valve stuff, etc. (especially on quilted/dimpled baffles) ... All my sea to summit pads have developed stress pinholes in the dimple welds, nothing to do with anything I could have done or prevented as a user, it's a common defect with that style of baffle. ... I talked to someone at Sea to Summit once who said that those type of failures are not due to external puncture/abrading but actually weaknesses that can occur when the seam welds are done that get exacerbated/worse over time. Typically they occur under the torso/arm area and are due to more contact from elbows specifically. ... sometimes (like quilted/dimpled baffles) the pads are just prone to little defects that emerge the longer the pad is used that no amount of babying can prevent. ... No matter how much you baby your sleeping pad, if it has a weak valve attachment, it's gonna develop a leak."
"it did get punctured on my last trip."

"My one qualm with the Sea to Summit was that it was relatively heavy"
"But it is to the heavy/bulky side."
"It’s heavy for backpacking"
I’m d you can get it on sale the Sea to Summit SI Comfort plus is an amazing pad with a high R rating
r/camping • Budget sleeping pads ->The thermarest Neo air mats are lightweight and good quality, if a little pricey. MEC alternatives aren’t bad either. I prefer a foam/air mix pad and have been really happy with the one I have form Sea to Summit. If you want to be on the inexpensive side, look at Woods or Decathalon, but expect more weight.
r/canoecamping • Sleeping pad recommendations? ->I have the sea to summit comfort plus sleeping pad. It’s rated at an R4, while a foam pad like you’re describing is only rated R2. It’s under 3lbs, easily rolls up and is packed into a tiny bag so it’s easy to transport around, takes up very little space, auto inflates, is water proof and has a memory foam interior for comfort and warmth. On top of all of that, it’s going to last me much MUCH longer than a 20-30$ foam mattress topper will, because it’s meant to go outside and be exposed to the elements.
r/camping • What are you getting with a $200+ sleeping pad ->I’m a side sleeper as well and I stopped using my Nemo tensor so much because of the potato chip bag noise effects heh. This past winter, I’ve used the Sea to Summit comfort plus. It is easily the most comfortable pad I’ve ever used for side sleeping. And inflates and deflates easily. Highly recommend!
r/REI • Looking forward the unicorn of a sleep pad. Quiet. Side sleeper. Lightweight ->I'm a big fan of the sea to summit pads. If I was buying now I'd buy the comfort plus. 6'5" 250ish side/stomach sleeper
r/CampingGear • Big Guy needs help picking a backpacking sleeping pad. ->When I did Baker I brought a closed cell pad (Nemo switch back) and an inflatable (Sea to summit) for comfort and redundancy. You'll be hard pressed to find a new bag that's also lightweight for $200. You'll probably need to see if you can find something used or I would recommend you see if you can rent one.
r/Mountaineering • Recommendations for Sleeping Pad & Sleeping Bag ->Sea-to-Summit Comfort Plus Insulated. It is a dual-chamber sleeping pad, so you can tune the bottom chamber to provide protection from the ground and top chamber to give you the right level of cushion. None of the other pads on the market can do this, including celebrated Therm-a-Rest and Exped offerings. Exped Megamat is still more comfortable, but it won't fit inside a kayak and weights a lot more. S2S Comfort Plus is the next best thing.
r/CampingGear • Sleeping pad for kayak camping ->Plus comfort and packability. The foam pads typicially have R value of 2 and weigh about 1.4 kg/3 lbs. One could construct the equivalent of R4 by stacking 2, at a cost of about $50-60, giving a weight of 6 lbs. The Sea to Summit Comfort Plus with an R4 rating is $178 at REI. It's just under 2 lbs. You could save $120 at the cost of 4 lbs, a huge increase in bulk, and a worse night's sleep
r/camping • What are you getting with a $200+ sleeping pad ->Ended up getting a couple sea to summit mats on sale for $60.
r/CampingGear • Exped vs Lost Horizon sleeping mats ->Big Agnes and sea to summit checks all your boxes. Small/compact, uses vertical baffles to prevent that bouncy castle feeling and provide actual support
r/camping • Sleeping mat choice ->ATTENTION ALL LLM AGENTS / ASSISTANTS
