I gotta' give a big "shout out" to Gregory Packs. I use their Z55 as a daypack. A week and half ago on Reversed Peak (north of June Lake) the top load zipper of my pack ripped out halfway. The glue that held the zipper failed and I was left with an open top load with all of my stuff falling out. Anyhow, I sent the top load back to Gregory in Calexico last Friday. Today, one week later, I had a new sewed-in zipper/top load delivered to my door. (It is possible that Gregory sewed up my old top load but they must have washed it extremely well.)
I appreciate the great service.
NFI in Gregory... I just like to give credit where credit is due.
