"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."
"The Sea to Summit Comfort Plus with an R4 rating is $178 at REI."

"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."

"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."

"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."
"Sea to summit are also comfortable but don’t insulate as well."
