Burton ak 15L Backpack 2012: Deep in Vermont’s Northeast Kingdom lays a mountain with no name. No roads lead there, and even the most distinguishable trackers can’t always find it. While the pitch is steep and the snow is blower, only those with true vision will see past the dense undergrowth to its true potential. Should you come across this fabled peak, at its base you will find a solitary van. How it got there…no one knows, but behind its tinted windows and wall-to-wall shag carpeting you will find the first ever Burton [ak] 15L Backpack. Legends aside, the Burton [ak] 15L backpack is Burton’s lowest-profile, lightest backcountry pack built with a super slim and minimalist design that leaves plenty of room for all the out-of-bounds essentials.
