Ok, first…I have a lot of pictures showing my first impressions on the hyperlites…M and MW versions, comparing to UL7 and also working with an Enlightened equipment accomplice double quilt here ->
(it was kind of buried in an REI 20% coupon thread)
Anyway, I received my synmat winterlite M today. Man…exped really needs to get on the ball and fix all of the data on their pads…the winterlite is worse than the hyperlite with the data discrepancies…
Can you spot all of the inconsistencies here? ->

For starters….weight.
REI lists the winterlite M as 14.3oz
Exped website: 14.3oz
Backcountry: 13.9oz
Exped box: 14.3oz
Actual weight: 15.15oz?
Rvalue:
Box: 4.9
Tag on mat: 6
rei: 4.9
exped website: 4.9
backcountry: 6
Insulation:
Retail Box: 160g/m2
Exped website: 200g/m2
I called Exped and they confirmed that the pad should be listed as 4.9rvalue…everyone should ignore the tags that are on the inflate valves. CSR said he would have to check with the engineering team to find out what really is the insulation value (160g or 200g/m2) though that doesn't really matter….just the rvalue does. Also get back to me on why mine is so out of spec on weight. (who knows? Maybe I really do have a 200g/m2 version that is rvalue 6…). I should receive an email back from exped tomorrow hopefully with some answers.
For other first impressions, you'll see that the winterlite series uses a 6 baffle system instead of an 8 baffle.

Not sure what differences that would cause, or benefits of one vs the other system…
But, I can tell you that the winterlite is definitely thicker. Its hard to measure exactly how thick it is or where exped measures, but I definitely believe the claimed 3.5" thickness:

I did notice a difference when laying down…but only really at the hip (and thus..only on one side since I'm a side sleeper), so on the hyperlite, if I bounce my hip a bit I can lightly feel the ground momentarily and I can feel that I'm still dangerously close to feeling ground. On the winterlite…I never hit the ground even after bouncing. I might have to keep the hyperlite a bit more inflated to make sure I don't touch the ground. I do have bony hips though….
And yes…the winterlite also does not have insulation in the side baffles. At least I can tell that the winterlite does indeed have much thicker insulation (more opaque):

hyperlite

My initial impressions were fine….I think the thickness is nice and the rvalue is a nice bump up from the hyperlite. But the weight really got me…I wasn't prepared for 15.15oz. If it was near spec (lets say, somewhere at 14.5 or less oz), then I would have been perfectly accepting of the pad. I'll have to hear what exped has to say tomorrow.
