"I've personally found the Ether Light XT Extreme to be pretty quiet. ... Nope! I’ve used the Ether Light XT, Ether Light XT Insulated, and Ether Light XT Extreme: all three are very quiet."
"The Ether light has a layer of foamy stuff rather than metal foil, so it is a lot quieter."
"At least the XT insulated I bought last year is silent, not a even a hint of crinkling."

"Another feature I love about the Sea to Summit is that their storage sack is also the pump sack. I’ve often forgotten to bring my Big Agnes pump sack when I’ve had my Rapide with, whereas that never happens with the S2S one."

"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."

"had multiple get air leaks in all the seams so I gave up on using it."
"which started leaking after 3 nights"
"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."

"I had to return my Etherlight XT since it was too cold to use even in summer."
"It's so cold with a quilt, It really feels like it's doing nothing, even in summer conditions."
"Same! ... I loved the feel of that pad, but I thought mine was defective!"

"Dropped about 9ozs and kicked myself the rest of the way down the trail for being so gullible. ... I could really feel those 9ozs off my back."
"The only downside is the bulk. ... It takes up a lot of space in my pack. ... When I I’m out for long hauls I don’t have the room for it and switch to the Tensor All-Season."
"It's heavy (21.1oz in the long wide version) and bulky"

"I had to return the etherlite after waking up with a sore back every night."
"even the 3” thick inflatable pad is barely tolerable."
"Air pads feel more bouncy and I find it harder to roll over, etc, which is honestly hard enough later in pregnancy."
