Mountain Hardwear Scrambler 25 Pack vs Zpacks Arc Blast

On the back, we've got these nice dual density foam shoulder straps a nice wicking fabric here on the back panel. on the inside of the shoulder straps...

Buy “durable” gear that you’re comfortable with, and let experience guide future choices. I’ve hiked for ten years with heavy and durable gear in my personal life and in the army - now i have an Arc blast pack and sleep on an Uberlight. It’s durable if you know what you’re doing, not cutting new trails through briars, and not sleeping on broken glass.

It fits me fine (keep it tight, as it's meant to sit above your harness), but the torso might be short for exceptionally tall people. I am a medium on most backpack scales, and it's perfect for me, as you might expect. Shouldn't be a problem for small torso people, but it might be worth trying on if you have a very tall torso. The 35 L version has a Large option, so that could be an option

I bought a used large Mariposa but find that when it's heavily loaded it hits my ass, no matter how I adjust it. I love those packs but haven't quite figured out the fit and I can't really return the used gear.
