guess I forgot to mention the straps in that last post. ill cover those here. the rev x comes with two sets of straps, 20" a foot box zipper and three snaps above the foot box for closing around your legs. I really like that the straps clip on, giving me the option of what I want to use or not with out having to cut stuff off. I can simply unsnap them. one set of straps are for attaching to your sleeping pad. I haven't really played with how yet and don't really think that's the route I will go with this quilt. the other set is for connecting one side of the quilt to the other as I have shown and have a huge amount of adjustment in them. in testing I found I like just the top strap behind my shoulders. as its easy to snap and adjust and keeps the quilt wrapped nicely around me. I was able to roll on my side inside the quilt with ease and stayed covered up nicely. the foot box and snaps are also a really nice design. again giving a lot of flexibility on configurations. when zipped up and all three snaps done up your legs are fully wrapped but theres still plenty of room to move around. I wear a size 13 and have some pretty long legs at 6'5" and I fit in this thing with a ton of room to spare, could easily pull it up over my eyes before I felt any stretch on my feet.the snap and draw string at the top are well designed also. very easy to snap and adjust from a laying position and again keep the quilt nicly formed around you while moving
