Detailed Product Description

Sized for grab-and-go afternoon adventures, the Inertia 20 keeps a low profile and clean exterior that won’t slow you down as you tear up the trail. Bring a rain shell, hat, and gloves for changing conditions in the fall and spring, or a suit and towel for summer escapes to the swimming hole. Leave your water bottle behind and fill up the included Gregory 3D Hydro reservoir instead for convenient hydration on the move. Show More Show Less
