Gregory Inertia 18 H2O Hydration Pack - Men's
When the early morning mist clings to the ridges and the path ahead promises elevation, the Gregory Inertia 18L Hydration Pack becomes an extension of your intent. Its dynamic fit ensures the pack moves with you, not against you, thanks to a suspended backpanel design that circulates air, keeping your core cool even as the climb intensifies. With 18 liters of streamlined capacity, there’s ample space for a light shell, essential layers, and trail sustenance, all secured by side compression straps and easily accessed through front and side stretch pockets. Trekking poles can be quickly attached or stowed, leaving hands free for scrambling. Gregory delivers a pack that’s not just about carrying gear, but about empowering fluid, unencumbered movement across demanding terrain, making every mile feel lighter.
