- The pack should keep water out in typical backpacking conditions where the pack is not submerged or exposed to prolonged periods of heavy rain. We still suggest using dry bags or a pack liner to protect important items like your clothing and sleeping bags.

Weight: The weight is displayed near the add to cart button. It changes depending on the options you select.
Included foam sit pad: 11" x 15.5" (28 cm x 39.4 cm) / adds 1 ounce (28 g) to the total weight of the pack.
Belt (optional): 1" (2.5 cm) wide x 50" (127 cm) circumference
Body dimensions: 5.5" x 11" x ~18" (14 cm x 28 cm x 46 cm)

Load Capacity: Recommended up to 20 lbs (9 kg) for shoulder comfort. The backpack materials can handle as much weight as your shoulders can for longer carries.
Torso Height:
This backpack has a single belt attachment position. The actual distance on the pack from the bottom of the belt to the top of the shoulder straps is about about 18" (46 cm), which will fit most adults. On a frameless backpack, it is nice to have the shoulder straps roughly level with the tops of your shoulders (rather than wrapping up around them) so that more weight is forced on to the webbing belt. The pack body does not extend much above your shoulders and load lifter straps are not needed.
Shoulder Straps:
Small/Women's Straps |

The straps have a daisy chain for clipping on items like our popular shoulder pouches, shoulder pouches w/ zipper, water bottle sleeves, and an adjustable position sternum strap is included.
