Mac's has the Millennium turkey chair on sale. It is very well built and light.
Uuuuuumm, 6.4 lbs is nowhere in the vicinity of being light
Foldemup, I have one and I would've never guessed it was that heavy. Its an easy carry, may be because its compact...
I will have to weigh mine before I believe its over 6 pounds. I would guess more like 4, and the way the strap fits and the mesh rests on the side of your hip, it is very very easy to move around with.
