A high-performing mountain bike pack providing stability and comfort on the gnarliest of trails, the Siskin 8 Men's Hydration Pack allows you to bring just what you need (and nothing more) on your ride.
A direct-access zip path leads to an included 2.5-liter reservoir, and a U-zip main compartment opens wide to stuff a spare tube, flat repair tools, and your PB&J inside. A mesh-covered foam back panel offers ventilation and allows for lively movement while keeping your pack close to your body, even when you’re riding loose.
