In my eternal search to find the right pack for me, I'm considering the Granite Gear Nimbus Trace Access pack in either the 60 or 70 liter size. Something for carrying loads between 20 and 40 pounds but occasionally quite a bit more if I'm hauling forestry tools. I like the fit, which is rare enough for me. I've tried Ospreys and Gregorys and mostly thought they were uncomfortable.
The unique thing about the pack seems to be the "maple core" framesheet. Not quite sure what that means, but it felt stiff and strong in the store. Would be interested in people's opinions from real world use.
Also, any experience dealing with the company itself? Good customer service?
