Light, durable, precision-fit 18L Hadron LCP pack for fast and light day hikes.

Light, durable materials. Access and organization. A highly adjustable fit. The Aerios 18 carries your day’s gear so you can move through the mountains with agility and comfort. The ultralight – but highly durable – 210D Hadron LCP (Liquid Crystal Polymer) pack fabric resists abrasion from granite and grit. Interchangeable harnesses let you find your fit, can be precisely adjusted using our patent-pending two-point system, and have secure front pockets for soft flasks and smartphones.
