The pack carries loads of 30 to 40 lbs, and the S/M size weighs 4.613 lbs with a volume of 3967 cubic inches.
Organization includes stretch mesh side pockets for water bottles, an internal hydration reservoir sleeve, a zippered sleeping bag compartment with removable divider, dual zippered hipbelt pockets, and a Stow-on-the-Go trekking pole attachment.
