Gregory Mountain Products Z 40 Backpack

Somewhere in between a daypack and a weekender lies the Z40, ready to crush a one-day ridge epic, support a winter summit attempt, or carry your warm-weather overnight setup through the desert. Side and bottom compression keeps smaller loads locked down for shorter outings, expanding when needed to gulp down rainwear or bulky layers in variable, wet, or cold weather.
