We barrel our way into the backcountry with Ashers 65L Backpack behind us. We're taking it along because it has a superior strength that ensures it won't tear open if it contacts a few sharp rocks. The Asher is built with a perimeter frame suspension that lessens that bobbing feeling some unsupportive bags give us. It's Amp - Flow back is probably our favorite part. It pulls air in to cool us off — which is nice after a 15 - mile day.
