Use the infographic table to help find the right sized pack for your trip.

Customize the Fit

Step 1: Hipbelt

  • Put the pack on your back so that the hipbelt is resting over your hip bones.
  • Close the hipbelt buckle and tighten it. (You should feel most of the weight of the pack on your hips, not your shoulders.)

Step 2: Shoulder Straps

  • Pull down and back on the ends of the should straps to tighten them.
  • Shoulder straps should fit closely to hold the pack body against your back, thus keeping the load forward. Your shoulders should NOT be carrying the weight.

Setp 3: Load Lifters

  • Load-lifter straps are located just below the tops of your shoulders (near your collarbones) and should angle back toward the pack body at a 45-degree angle.
  • Gently tug the load-lifter straps to pull weight off your shoulders.

Step 4: Sternum Strap

  • Adjust the sternum strap to a comfortable height across your chest as needed.
  • Buckle the sternum strap and tighten until the shoulder straps are pulled comfortably inwards from your shoulders, allowing your arms to move freely.

Final Tweaks:

  • Pull the stabilizer straps (if equipped), located on either side of the hipbelt, to snug the pack body woard the hipbelt and stabilize the load.
  • Go back to the shoulder straps and carefully take a bit of tension off of them. This ensures the majority of the weight is carried by your hips.
