Looks chilly but beautiful.
I've had the same thing with an Exped SynMat UL7. The baffle didn't split all the way, just a few feet at the end. The warranty guy (for Canada) was great though, I just emailed him a photo of mine and he mailed me a replacement pad.
I don't find the SynMat 7 to warm enough once ground temps dip below about 25-30F, so that might have been part of it. I find a similarly R-value rated NeoAir to be good to about 5 degree cooler, but I prefer the comfort of the SynMat design.
