Arc'teryx Aerios 18 Pack - Unisex

Move fast, move light, and stay comfortable with this precision-fit pack built for technical day hikes. The Aerios 18 blends an ultralight feel with rugged trail performance. Its Hadron® LCP fabric is tough enough to resist scrapes, drags, and snags, and sheds light rain thanks to a PFC-free DWR treatment. A patent-pending interchangeable harness system fine-tunes the fit across a wide range of body types, keeping pockets perfectly placed and loads stable.
