Great warm weather pad.
Warm weather it's great. But I just spent one night in the upper 30's on this thing. It is NOT for the 35 degree weather that it is rated for. Even with a layer of Capilene 3, pants, tee, heavy fleece, and a BA Summit Park 15 degree bag I froze. Would not use it again below 50 degrees or so at least with any Big Agnes bag without a closed cell pad. And then you might as well of had an insulated pad instead. Comfort, small roll up size, weight and durability get a 4.5 out of 5 though.
I purchased an Exped SynMat 9 Deluxe for the BA Summit Park and it rocks in colder weather. A little heavy, but a bigger comfy bag and pad are the two luxuries I refuse to compromise on.
