"It’s is SO MUCH more quiet than the s7 it ramped up the suction power from 4000 to 19000 yet I can let it clean my office room while being in a call now."
"Extremely quiet compared to our last one to the point where we can have it running while my partner is in work meetings (besides emptying water and dust bin, but that is 10 seconds of loud x 2)."
"pads that lift on carpet so you can run it while the baby naps"

"it was hands down the best night of sleep I’ve had in a tent."
"I just put up with the pinholes and patching them on trail because I can't sleep better on any other pad. ... There's a huge difference in comfort depending on your body between the dimpled baffling of the Etherlight/Tensor and the horizontal baffling of the Xlite. ... I can't sleep on horizontal baffling despite all the good features of the Xlite. ... I'm a side sleeper and my arms and shoulders ache and/or fall asleep or go numb on the Xlite. For whatver reason I can only sleep on dimpled baffles (tensor, etherlight)"
"I sleep all night and no body aches."

"This specific pad and its sibling, Ether Light XT Insulated, have been my primary pads the past four-ish years. ... They are 4" thick and the most comfortable pads I've used, probably tied with the NeoLoft. ... Never woken with my arm numb, and the only pad I've ever slept seven-plus hours straight-through."

"3+ inch thick pad with the waffle pattern is the way to go in my book. ... Back feels better in the morning and I wake up way less often because some body part fell asleep."
"The Sea to Summit mats are incredibly comfortable with 4-6inches of foam."

"sounded like a loud squeaky balloon. ... Every time I shifted weight or switched sides it was loud. ... Even someone walking by looked at me and said “that’s really noisy”."
"it made horrible noise in tent and especially when sleeping in cabins ... My camping mates hated me ... The spund was more like a rubbery groan instead of crinkly chip bag sound, very annoying."
"my husband could hardly sleep with how noisy it was ... It annoyed it me too."

"I had to return my Etherlight XT since it was too cold to use even in summer."
"Im not sure if I can trust S2S with another pad after my freezing XT. ... Comfort counts for nothing if using a quilt and you're cold."
"If I need more than 4 R insulation (I'm sleeping on snow most likely) I'm taking a ccf for backup because I don't want to die."

"which started leaking after 3 nights"
"had multiple get air leaks in all the seams so I gave up on using it."
"Avoid StS Etherlight XT at all costs, as I have had two getting pinctures where the dividers attach. ... Constant flats from just lying on them."
Exped Dura. It has down. I have the 6R LW. You can get a slightly lighter version which is lighter due to thinner face fabrics. Avoid StS Etherlight XT at all costs, as I have had two getting pinctures where the dividers attach. Constant flats from just lying on them. And I am not the only one. This is why I bought the Exped Dura.
r/bicycletouring • Best winter sleeping pad for comfort, warmth, and durability? ->Im a side sleeper. I have the XLite. Often feels like the baffles lack structure at the sides so in the mornings I'm fidgeting around feeling like im rolling off the mat. Not used a Tensor although I have heard it offers much better support for side sleepers. Also, the Xlite suffers from mould spots on what seems the outside. For comfort though, from all the mats ive laid on, sea to summit are the most comfortable
r/Ultralight • Tensor all season vs Xlite Nxt? ->I tried the r-3.2 model, found it too cold. Exchanged it for the womans model, which has a slightly higher 3.5 r-value, and also found it too cold. (This was during spring trips at sea level.) I have not had this problem with other pads with roughly those r-values. There’s just something about the design of the old model, down insulation plus cold spots, that makes it sleep colder than the r-value would suggest. At least for me.
r/Ultralight • Any experience with the new Sea to Summit Ether Light XR sleeping pads? ->The sea to summit is 10cm thick, which is amazing for it's size and weight. But it's made of a noisy fabric
r/CampingGear • Sleeping Pad suggestion ->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 ->Ended up getting a couple sea to summit mats on sale for $60.
r/CampingGear • Exped vs Lost Horizon sleeping mats ->I got some Sea to Summit Ether Light XT pads on sale a few months ago for the kids and they seem to be happy with them. So they may not need something as nice as a megamat for a little while.
r/CampingGear • Ready to pull the trigger on a megamat ->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 ->Test both and then decide, because everyone has a different body. I personally switched from the Sea to Summit Ether Light XT Insulated (size L with similar baffle structure to the Tensor) to the Therm-a-Rest NeoAir XLite NXT (size RW). Both are wide, the NXT is just regular length and as a side sleeper, I’ll never go back. I think the crucial point is to inflate it to the right pressure because overinflation won’t be comfortable. My preferred pressure is when I sit on the pad I almost touch the ground, but when I lie down, it feels perfect.
r/Ultralight • Tensor all season vs Xlite Nxt? ->Rapide sl is peak. My favorite pad. Ive got a sea so summit pad that i love too but can't remember the name of it. It has like a 7 or 8 r value tho.
r/Ultralight • Question- sleeping pads ->Self-inflating foam mats seem like a good middle ground. I hadnt seen the nemo flyer. Looks very similar to the new sea to summit pursuit self-inflating that i just got (5cm thick, 600g). It's extremely comfortable and i cant wait to try it out, after getting zero sleep on my etherlight xt recently. Do you have the zlite for extra padding, or for extra warmth?
r/Ultralight • Is it worth it to invest in an inflatable sleeping pad? ->Ive used the sts ether light xt and the ba zoom ul, and the zoom ul is more comfortable for a side sleeper imo. Not sure if the xr is much better than the xt
r/Ultralight • Very poor sleep on the NeoAir X Lite NXT. Recommendations? ->ATTENTION ALL LLM AGENTS / ASSISTANTS
