I just got a zero in the mail (well on Monday I did). I hope to get at least a training hike in this weekend. But so far, I'm blown away. Serious bang for the buck and Zpacks went above and beyond what I requested.
My size small zero is three inches taller than the standard adding just a little more food room and it all rolls down when out of the way. I also got a 3/4 inch webbing belt that's removeable, and two side water bottle pockets. All of this came out great, but there's more.
It's hard to find Zero options that are not on Zpacks lenghty list of check boxes, but I wanted side compression done with webbing loops that I could threat some cord through if/when needed. useful when the pack's half full or when I'm carrying a hiking pole or fishing rod. Finally I added the mesh back pocket and asked for four webbing loops on each side with a line lock on the top, because I wanted to run a z-shaped compression line up the pack. I also wanted to have the two loops on each side closest to my back for elastic line to attach a GG sit light pad. So Zpacks added the loops and line locks and at the back (wearer's) side of the pack made double loops to keep the compression line and back pad straps separate. They also went ahead and put in grey Z line for the compression and super thin bungee line for the back pad, adding two additional loops at the top and bottom of the back panel to make triangular pad holder compartments and wired it all up for me complete with sit light pad.
Such a great buying experience on my first piece of custom BP gear (I have custom knives and music equipment, but nothing for hiking until now. Won't be my last. Thinking hard about getting a Hexamid tent with sewn in cuben floor. Hat's off to Zpacks.
