What would you like to know? I've had mine 4-5 years I guess. I got the XL because the hoop is a bit higher giving more clearance between my face and the mesh. It's more than plenty long and plenty wide. I'm hard-pressed to find anything to complain about. I suppose this may sound odd, but one thing I don't like is the tub material is so slick that when I've folded the bivy, it's hard to keep ahold of it to chase it back in the stuff sack.
Every hear the term 'mud wrestling with a fat girl'?
It doesn't sound odd at all. Sil-nylon can be darn near impossible to stuff sometimes.
