Learn how to attach the Flight Shoulder Harness to your Six Moon Designs pack. Follow these steps for a secure, comfortable fit on the trail.
Quick answer
Attach the Flight Shoulder Harness by threading the pack's webbing through the harness channels, securing the sternum strap, and adjusting the load lifters for your torso length.
Why the right attachment matters
A properly attached harness distributes pack weight evenly across your shoulders and hips, reducing fatigue and improving stability. The Flight Shoulder Harness is designed specifically for Flight Series packs, so the attachment points align perfectly with the pack's load-lifter system. Skipping the fit check can lead to pressure points or an unstable carry, especially on uneven terrain.
Step-by-step attachment process
- 1. Locate the attachment slots: On your Flight Series pack, find the two vertical webbing channels on the back panel where the harness connects. These are typically at the top of the frame, near the load-lifter attachment points. Check that the harness's webbing straps are not twisted before threading.
- 2. Thread the harness webbing: Insert the top of the shoulder harness strap into the channel, pushing it through until the buckle end emerges at the bottom. Repeat for the other side. Ensure the harness sits flat against the pack. If the strap doesn't slide easily, don't force it—gently wiggle it through to avoid damaging the fabric.
- 3. Secure the harness buckles: Clip the harness buckles into the corresponding female buckles at the bottom of the pack's frame. You should hear a distinct click. Tug gently to confirm they are locked. A loose buckle can cause the harness to detach under load. Double-check each connection.
- 4. Adjust the sternum strap: Slide the sternum strap up or down along the harness's webbing to a comfortable position across your chest. Fasten it and adjust the tension so it sits snug but not restrictive. Position the sternum strap about 1-2 inches below your collarbone for optimal load transfer.
- 5. Set the load lifters: Connect the load-lifter straps from the top of the pack to the harness's attachment points. Tighten them evenly so they angle back at about 45 degrees, pulling the pack close to your body. Over-tightening load lifters can lift the pack off your shoulders, creating a gap. Aim for a snug, even pull.
- 6. Test and fine-tune fit: Put on the pack with some weight. Walk a few steps and check for pressure points or shifting. Adjust the sternum strap and load lifters as needed. The harness should feel secure without digging in. If the harness feels loose after adjustment, revisit the webbing threading—it may have slipped during initial setup.
