Keep the good times rolling.

You know the feeling, it happens maybe twenty minutes after the trailhead—that nearly indiscernible moment where you find your groove and feel as though you're able to hike for miles without pause. As its name implies, the Gregory Inertia 25 Backpack keeps the good times rolling, for it comes with a padded hipbelt and shoulder harness that makes long distances feel short, and its back panel is lined with mesh for ventilated comfort when you're working up a sweat.

Plenty of features enhance your time on the trail, from the included reservoir that makes on-trail hydration nearly hands-free, to the trekking pole attachment that keeps your poles out of the way during flat stretches. A magnetic closure on the sternum lets you link your bladder's bite valve to it, eliminating the annoying dangle where it flops all over the place while you're hiking, and the bite valve itself features an easy on/off switch so you're not leaking water everywhere either.
