TrailRunner 2L Hydration Pack in Arcadia

The ergonomic fit is spot on—I barely notice it bouncing when I’m climbing, and the 2L bladder sits snug against my back without sloshing. For the price, it’s held up through muddy, rocky miles so far.

Didn't expect the 2L to disappear on my back like that—the ergonomic fit keeps it snug through steep climbs, and the whole thing feels light enough to forget it's even there. Charged through a muddy 8-miler and the pack stayed put with zero bounce.

The chest straps sit snug without chafing, and the 2L bladder tucks in tight enough that I forget it's there on climbs. First run with it felt balanced, not bouncy.
