In reply to kevinroet:
I posted this in a December thread
"Had a Zenith for approx a year; good sack, very well made, comfortable and lighter than it looks.
My only complaint is that the closing straps are stitched quite high up so that if you're climbing with it fairly empty, it's difficult to strap the lid down tight. I get around this by threading the straps down through the axe attachment loops."
