◄Features

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.     
• U-Flow system ensures that the hip belt follows the natural movements of your hips. The hip belt is held by a central point to the main body of the pack, allowing the hip belt to both rotate side to side with the hip movement and pivot forward, away from the bottom of the pack. This increases your balance and agility and reduces the accumulation of fatigue on your body.    
• The structure of the hip belt ensures an optimum load transfer towards the hips to lessen the pressure on the shoulders.    
• The breathable 3D mesh used on the upper part of the hip belt wraps perfectly over the top of your iliac crest, offering superior comfort and support for long hours on the move.    
• Quick-release buckle allows you to easily unclip the belt with one hand.    
• Attachment points for interchangeable Balance Pockets. 

Suspended Mesh Back Panel:    

• Auto-moulds to your back shape.    
• Maintains an air gap for back ventilation keeping you cool and dry.

• One main top compartment and a small compartment accessible from the bottom of the pack.  
• Slim side profile to reduce the backward pull on the shoulders.    
• Extendable and removable lid,which doubles as a bum bag.
