Familiarity: I've used it several times
Another super bomber pack from the good folks at BD. The material feels solid and holds up well to scrapes and general pack abuse. It's not the most water-resistant I've found, but I always have a trash bag liner anyway, so no big deal. I love the Swingarm suspension and how it hugs your body rather than staying rigid on your back; the shoulder straps are pretty thin, but the pack isn't designed for super heavy loads so I don't notice them rubbing, plus the pack carries so well that there's not much weight on your shoulders anyway. I'm also a big fan of the padded bottom. God knows I've accidentally dropped my pack a bit too hard a few too many times so it's nice having that little extra padding and durability. Also the buckles are gloves-on-compatible-for-unbuckling. Super nice for cold days.
The hipbelt is a bit of a PITA to take on and off, the expansion collar is way too big IMHO, and the adjustment buckles on the shoulderstraps and brain have two different ways to thread them, one locked and one free to slide, but they're all things that I've figured out how to resolve and/or deal with efficiently.
All in all, super solid pack full of hidden secrets (okay just one - the tucked away rope strap) but yeah, I love it.
