Sizing Chart: 


Pared down to the essentials, this go-anywhere alpine pack is for super-minimalists who make every gram count. Perfect for light and fast blitzes from an alpine base camp, the entire pack stows into its lid pocket. The exterior elasticized shock cord lashing system also works to compress the pack's volume, ensuring a trim and tidy profile. The top-loading lid snaps securely in place with a single-point buckle. This pack is ideal as a secondary pack on alpine expeditions, backcountry treks, or kayaking adventures.
