"I was like OP and had the Klymit but then switched to the Sea to Summit ultralight insulated pad (oval shape) a year ago and it’s been amazing. ... I used my Klymit again last month on a father-son trip and the difference in comfort is noticeable."
"I have the Sea to Summit Ultralight Insulated pad and I find it quite comfortable. ... I’m a side sleeper and it feels comparable to a normal bed at home."

"Yes. Camped in around -7 deg C in the snow with it as a longer trip shakedown. No issues with cold due to the pad ... Also on the PCT we started in late March so we had cold nights (close to -5 C) in the desert including adjacent to snow around San Jacinto."

"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."
"The most comfortable backpacking pad I've found is the sea to summit light because it has a lot of small baffles instead of long continuous tubes like most pads. That makes it a lot more supportive."
"The Sea to Summit mats are incredibly comfortable with 4-6inches of foam."

"Sea to Summit ultralight pad had nothing but punctures (or material defects) for me over the years."
"My new fucking Sea to Summit Ultralite decided holding air is not its thing despite very careful handling and making sure it wasn't left inflated during the day."
"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."

"The biggest issue is the noise it makes, I move a lot from side to back and vice versa during the night. The noise sounds like balloons rubbing against each other. I've tried wrapping it in a blanket, which helps a bit but still makes a lot of noice."

"The second problem is that, even when the pad is fully inflated, my hip bones still slightly touch the ground which is uncomfortable and make me change position even more often."

"I’ve used a S2S Ultralight Insulated for years and it’s done a pretty good job but the mummy shape is not ideal for how I like to sleep. I always end up with a leg off (and freezing) or struggling to find a comfy position."

r/WildernessBackpacking • How much better are “nice” sleeping pads? ->Seems relatively heavy. The Sea to Summit Ultralight Insulated Air Sleeping Pad is much lighter but cost more. [Sea to Summit - Ultralight Insulated Air Sleeping Pad](https://seatosummit.com/products/ultralight-insulated-mat?variant=7896105451548) This was my first inflatable sleeping pad, it was a work horse. The S2S has a slightly lower R value, it’s 1.5” wider and has the same thickness. I got the S2S for like $70 at the beginning of the pandemic, and it’s been a great value. I’ve recently upgrade to a Therm-a-rest xlite. I think the sea to summit is a little bit too expensive now, it should be closer to the price of the Trail Pro light. The Therm-a-Rest xlite is a much better value but for a higher price.
r/Ultralight • Opinions or reviews of the newest therm-a-rest trail prolite? ->I've bought the Sea to Summit ultra light sleeping pad, and have a few problems with it. The biggest issue is the noise it makes, I move a lot from side to back and vice versa during the night. The noise sounds like balloons rubbing against each other. I've tried wrapping it in a blanket, which helps a bit but still makes a lot of noice. The second problem is that, even when the pad is fully inflated, my hip bones still slightly touch the ground which is uncomfortable and make me change position even more often. I am looking for something lightweight, but now realized how important a good night of sleep is. I am 175cm (5'8) tall and around 65kg (143 pounds). What would be a good alternative sleeping pad to try? Something without noise and maybe thicker/comfortable as well?
r/Ultralight • Noisy sleeping pad, what is a good alternative? ->Sea-to-summit. Expensive but good stuff
r/bikepacking • Best lightweight sleeping Pad? ->Ultralight insulated Air is the model i use, but there's more [https://seatosummit.com/collections/sleeping-pads?srsltid=AfmBOopTHS7LFp27EmtztP1MZpAchicKxS1C6JZdyuV8\_Hk0ZEySVc7N](https://seatosummit.com/collections/sleeping-pads?srsltid=AfmBOopTHS7LFp27EmtztP1MZpAchicKxS1C6JZdyuV8_Hk0ZEySVc7N)
r/bikepacking • Best lightweight sleeping Pad? ->Here’s a question that’s been asked a million times. I’m about to pull the trigger on a Nemo Tensor All-Season Regular Wide. I’ve done a bunch of research and it seems like the best option but I often discover new brands here so let me know if you think something would suit better! I care a lot about: - width, I’m a side sleeper and like to stick a leg out - stability, I don’t want to slide off the mat - weight, current pad is 350g which is nice - packability, I often do long hikes with a small pack - pump sack, I really like these I care less about: - warmth, current pad is 3.1R which is fine, in super cold weather I layer with CCF - noise, I don’t love it but I can live with it - features like being able to tie pads together, I go solo - price, happy to pay for the right mat I’ve used a S2S Ultralight Insulated for years and it’s done a pretty good job but the mummy shape is not ideal for how I like to sleep. I always end up with a leg off (and freezing) or struggling to find a comfy position. All advice appreciated!! Thanks!
r/Ultralight • Sleeping pad advice? ->6ft side sleeper, I can recommend the Sea2Summit ultralight insulated. Comfortable and light. Tried it side by side with my wife's Thermarest NeoAir X Lite and I found the S2S more comfortable as a side sleeper.
r/wildcampingintheuk • Best inflatable sleep mats? ->Same. I have a Sea to Summit Ultralight and I sleep so well on it… 2” thick, weight is 15 oz, R-value 3.1
r/motocamping • Sleeping pad comparison for motocamping and why air pads are optimal ->Sea to Summit ultralight pad had nothing but punctures (or material defects) for me over the years. Although their warantty is spotless, this doesnt help when you are traveling and you need a new pad immediatelly. Also consider if you plan using it in thorny landscape, you would be better with some kind of foam mat.
r/bikepacking • Best lightweight sleeping Pad? ->I have just upgraded my sleep system and bought the sea to summit 3.1 from sports pursuit and will be testing it out next week along with a Rab 500.
r/wildcampingintheuk • Sleeping mat recommendations ->Since a good part of how you want to use this is in airports, while you’re traveling, I agree with the suggestion of getting a “quilt”. They’re light, packs small and would give you more comfort and flexibility in fitting in where you can in the airport. I wish I’d thought of that - I’m remembering a long, overnight layover in Bogota Colombia. A problem I see is that you probably don’t want as much warmth for “Travel” backpacking as you would for “wilderness” backpacking. You’ll have to find the right balance that works for you. For a sleeping pad, I’m currently using a Sea to Summit ultralight mattress. It’s light and compact but probably not as inexpensive as it sounds like you’re looking for.
