U-Flow Shoulder Harness:
- U-Flow bottom shoulder straps allow free shoulder movement while ensuring optimal pack stability, reducing fatigue buildup, and increasing your balance.
- Breathable stretch 3D mesh that auto-moulds to the natural slope of your shoulders.
- Back length adjustable while wearing the pack for a dialed-in fit.
Dynamic Pelvic-Form Hip Belt:
- Dual-adjust hip belt tensioning system allows for fine-tuning of the hip belt.
- Hip belt angle is micro-adjustable to allow a perfect match to your pelvic shape.

This increases your balance and agility and reduces the accumulation of fatigue on your body.
