Aarn Natural Balance Pro offers exceptional load-carrying capacity with reduced pack weight. 

The perfect pack for those embracing the light and fast philosophy but needing a higher capacity than the Featherlite Freedom Pro

The new UHMWPE Gridstop model shaves off grams whilst still having a high weight-carrying capacity for longer trips. 


  • Dyneema Gridstop fabric.
  • New stronger Flow Frame with reduced weight.
  • Bio-Fit shoulder harness.
  • New side pockets.
  • New front pocket.
  • Roll top with water-resistant Dri-liner.
  • 12 accessory attachment points.
  • Cord-loc compression.
  • Hydration exit and attachment loop.
  • BACK SUSPENSION: The pro utilises a new stronger Flow Frame with reduced weight. The hourglass shaped frame maintains a slim profile when the pack is stuffed full yet the stretch back-panels can auto-mould to your back shape when the hipbelt is done up. Ventilation is outstanding with a suspended mesh back panel. Go here to determine your correct backlength.
  • SHOULDER HARNESS: The Bio-Fit shoulder harness has 2 sizes S, L . It's made of thick breathable mesh with a double layer over the collar bones. It stretches and auto-moulds to the slope of your shoulders. When the Flow-Thru stabilisers are tightened to bring the top of the pack close to your back there is no shoulder strap distortion. Our On-Adjust back length allows precision fit to a wide range of body sizes. U flow is by an interlinked cord running through a teflon tube for smooth friction-free movement.
  • HIPBELT: Pelvic-Form hipbelts come in 4 sizes, S, M, L & XL, and micro-adjust in length and angle to allow a perfect match to your pelvic size and shape. Dual-adjust tensioning allows fine-tuning of the upper hipbelt shaping around your waist and the top of your hips. The tension on the Multi-Flow cord which connects the hipbelt to the sides of the pack can be adjusted to vary the proportion of the packs load transferred towards the front of the hipbelt. U Flow via center pivot and interlinked side stabilizers.

About Aarn

Aarn Packs represent the most efficient, comfortable, stable, practical and healthiest way to carry load on the human body.

They challenge traditional thinking on pack design.

Aarn Packs was born in Aotearoa New Zealand, Mother Nature’s playground, where spending time in the mountains and on the trails is a way of life.

The founders Aarn and Devi Tate set out to challenge traditional back pack design thinking. They spent years researching, innovating, and developing new design principles to create a pack that didn’t alter posture, balance and movement.

Aarn Packs and Balance Pockets are designed here in Christchurch, New Zealand, and are available throughout the world. Aarn's design principles stay the same to this day, with a focus on posture, balance, movement, fit, lightness and using science to improve your comfort and health.

Aarn embrace the philosophy of the Cradle to Cradle method and keep sustainability in mind with their design and manufacturing processes.

Aarn Packs continues to be an industry leader in the outdoor adventure scene. We’re proud to have received accolades and awards from DuPont, Trail Kauftipp, Editors Choice at Outdoor, Outdoor Gold Winner, Gear Guide Innovation Awards, and ISPO Brand New Award.
