Gregory Inertia 20 Hydration Pack

Equipped with its own integrated 3L hydration system and weighing less than 1.5 pounds, the streamlined Gregory Inertia 20 pack is ideal for ultra-lightweight day hiking or spur of the moment adventure.

The pack has a mesh-covered, ventilated backpanel that cushions weight against your back while also helping to keep you cool and comfortable. Ventilated foam in the contoured shoulder straps adds comfort and support. An adjustable sternum strap, load-lifter straps, and a minimalist, removable webbed waist strap further enhance fit.

In addition to the panel-loading 1220 cubic inch-capacity main compartment there is a large front stretch pocket to keep discarded layers and other gear close at hand. Other features include stretch mesh side pockets, a small zippered and lined pocket that is ideal for sunglasses and electronics, and trekking pole attachment loops. A separate zippered pocket houses the included 3-liter 3D Hydro reservoir. This BPA-free hydration system has a rubberized fill port and a built-in handle that provide convenience when refilling. Three-dimensional construction allows the reservoir to fit more comfortably inside your pack than traditional unstructured reservoirs. A magnetic bite valve delivers an excellent flow rate and secures to the pack’s magnetized sternum strap to keep the drinking hose at the ready but out of your way when not in use.

The Gregory Inertia 20 hydration pack is available in your choice of color options.
