Why are Aarn Packs so Different?

Aarn Packs
The founders of Aarn Packs, Aarn and Devi Tate, embarked on a mission to challenge conventional backpack design. With years dedicated to research and innovation, they developed new design principles aimed at creating a pack that maintains natural posture, balance, and movement. Aarn's unwavering commitment to designing the most comfortable packs on Earth remains at the core of the brand's philosophy.
Thanks to its unique free movement harness and balance systems, Aarn Packs has established itself as an industry leader in the outdoor adventure community.
What Makes Aarn Backpacks Different?
Aarn backpacks feature ventilating back panels that prevent overheating. The pockets are equipped with bendable frames, minimising contact with the chest. By utilising Aarn backpacks in conjunction with Balance Pockets, weight is distributed evenly around the wearer's centre of gravity, eliminating the leverage effects caused by an offset load. This design ensures that posture and balance are maintained while requiring less effort and energy during transport. This meticulous attention to ergonomic detail results in a synergistic effect, enhancing comfort and energy efficiency.
Independent sports science findings (Ray Lloyds Sport Science on Aarn Packs and Tim Grigg Aarn Packs Sports Science in Detail) confirm that using an Aarn Balance Backpack allows individuals to carry their load with reduced effort and strain. A balanced load proves to be healthier, minimising strain and the potential for muscle, tissue, and nerve damage to the shoulders, neck, and spine. Numerous testimonials highlight that individuals who previously struggled with hiking due to back or neck injuries, pacemakers, or surgeries—such as breast surgery or lymph node removal—have successfully returned to the trails with Aarn Balance Backpacks.
Do Aarn Packs Reduce the Impact on Your Body While Backpacking?
Aarn Packs help reduce the strains put on your body by a backpack when hiking. The research's results were striking, showing significant advantages of wearing an Aarn pack over a traditional pack.
When walking wearing the Aarn pack, insignificant changes in posture were observed compared to walking without a backpack; lumbar flexion only increased by 6.24% and centre of pressure by 1.89%.
In contrast, when comparing walking with a traditional backpack to no backpack, lumbar flexion was increased by 40.35% and the centre of pressure increased by 12.26%.
The centre of pressure is also closer to its natural location while wearing an Aarn Pack compared to carrying a traditional backpack.
The Aarn pack encourages an upright posture that is less fatiguing on muscles, therefore improving performance over the long run. On the other hand, traditional packs tend to create an unnatural increase of forward lean in the torso, leading to additional stress and strain on the muscles used to keep balanced, specifically the lower back and hips. This is because the body needs to work a lot harder to stay balanced while in a “hunched over” position. Over prolonged periods of exercise, this additional work takes its toll, increasing the rate of fatigue and decreasing gait efficiency.
Aarn Ergonomics & Fit
Aarn Packs are obsessed with achieving the perfect fit and have invested decades into refining their designs to accommodate a diverse range of body shapes and sizes. With forty years of experience, Aarn has developed systems including multiple sizing options and unique auto-moulding techniques to ensure a fit that caters to the widest variety of body forms.
The key features of these systems are:
● Most models (including daypacks) have adjustable back lengths for a precision fit.
● The back panels on all lightweight framed backpacks Auto-Mould to your back shape.
● Shoulder harnesses Auto-Mould to the slope of your shoulders.
● Auto-Mould hip belts adjust in shape and length automatically as you wrap the hip belt around your pelvis.
● Pelvic form hip belts come in four sizes. The overall length is adjustable by 10cm (3.9in). The top of the hip belt wraps over the top of your hips to your precise hip shape.
● The back panel, shoulder harness and hip belt are highly breathable to minimise heat buildup.
*Aarn doesn't make separate men's and women's packs. The ideal solution is complete adjustability so you can achieve a mirror image fit to your unique size and shape, regardless of your gender.
Aarn U-Flow System
The Aarn U-Flow System is engineered to balance the weight of the Balance Backpack around the wearer's centre of gravity by aligning horizontal and vertical forces. This system connects the harness, hip belt, and balance pocket system, enabling free movement of the body.
The U-Flow System allows the shoulder straps and hip belt to move independently in tandem with the wearer’s movements, all while ensuring the pack remains securely attached to the back. This innovative design reduces fatigue and boosts performance under load, granting users the freedom to twist, rock, stretch, and bend naturally. With an Aarn Balance backpack, one could even dance without hindrance.
Aarn Balance Pockets
Aarn Balance Pockets provide a straightforward solution to minimising neck and back pain during backpacking. These pockets attach seamlessly to an Aarn Pack, balancing the load and reducing strain on the body, ultimately leading to a more comfortable adventure. Incorporating Balance Pockets or Universal Balance Pockets diminishes the leverage exerted on the shoulders and back caused by an uneven load. The result is reduced fatigue and a more comfortable carrying experience.
Furthermore, the easy access to gear provided by Balance Pockets allows users to navigate through varying terrains efficiently, without the need to stop and remove their packs. The energy savings realised from a balanced load outweigh the additional weight of an Aarn Balance Backpack when the total load of the pack and pockets combined exceeds 6 kg. Comparatively, when placed alongside an ultralight or minimalist backpack, the weight difference is minimal.
