Overview

Keystone 25 is a stealth 25L daypack built as a modular system: under-seat travel friendly, office-safe, trail capable - and designed to be serviced and repaired, not replaced. Most packs are either fragile, loud, or disposable. Keystone is the middle path: understated on the outside, engineered on the inside.
