Step 1: Load the pack with about 20 pounds, then loosen the hipbelt, shoulder straps, hipbelt stabilizers, and load lifters.
Step 3: Properly sized, there should be no gap atop the shoulders, and the load lifter anchor point should be at collar-bone level.
Step 4: The hipbelt should sit over your pelvic bones.
Step 5: Once the basic torso length, hipbelt and shoulder strap length is dialed in, snug the hipbelt stabilizer straps.
Step 6: Snug the load lifter straps for a more stable load.
Step 7: Fasten the sternum strap. Position it properly between chest and collarbone level.
Step 8: If the sternum strap is too low, it will restrict chest expansion and breathing.
Step 9: When correct, it will keep the shoulder straps from slipping outward during scrambles, while letting you breathe deeply.
