On Monday I received a Z1 pack from zpacks.com. The pack fully pimped out has these features:
Side compression straps,
Bottom compression straps,
Sternum strap,
Daisy chain on the shoulder strap,
zpack shoulder strap pouch,
zpack map case on the belt,
zpack snack bag on the belt,
Self installed shockcord bottle holder,
7.8 oz. fully tricked out.
Customer service was excellent and the craftsmanship is very good.
I have not had it out, but have packed it with an actual load and it was as comfortable as a sack with shoulder straps can be. I am very pleased.
