This is my 2nd Exped, and much like the SynMat 7 I own, this seems to be built well, warm and comfortable. During it's first 4 nights of use it never got below 40, but I can already tell it's adding warmth in a big way. I'm normally a sleeping bag zipped up guy, but didn't zip it once this past trip. Moreover, just resting your hand on the bare pad is enough to feel, within a few seconds, how warm and reflective of heat this pad really is. I have no question as to whether or not it'll hold up in zub-zero camping conditions later this winter.
After borrowing my brother's long/wide pad, I knew I was, in choosing an L/W over a regular, was opting for more space/weight. I'm ok with the little bit of added carrying burden for the pure comfort this pad brings to the table.
Having the schnozzel pumpbag was great. Taking only 7 or so pushes, it replaces minutes of blowing, which means I'm also not injecting hot, moist air into it in Mid February. Solid idea here that plays out well in the real world scenario. I was bummed that it didn't fit onto my SynMat to use on that as well.
I'm a side/back sleeper and much like other thicker air pads, this is comfy and brings side sleeping to camping. Between the extra heat, space and loft I slept like a baby. I'm not sure how you could create a warmer or more comfortable pad without adding size and weight.
My only 2 gripes with this pad aren't even with the pad...they're with the included storage sack.
-While it isn't HARD to get it rolled back up and into its stuff sack, it needs to be done perfect to fit well. It's harder than other pads I've owned which isn't a big deal at home...but when it's 6am and you're in -10 degree weather with 2 other people in a tiny tent I could see it being frustrating. I just think it needed a slightly bigger stuff sack.
-The stuff sack it came with is extremely fragile and while taking the pad out to test it at home, before it'd even been used, the pocket w/ repair kit pulled loose. I understand it's just a stuff sack, but anything over the $200 mark should include a case that's meant to stick around longer than day 1
