Paramo UK. Preliminary design of outdoor shell garment range using Nikwax Biological Analogy System.
Natural Balance, USA. Worked in a company to make my backpack designs. Ultimately, the company was unsuccessful but it served to develop designs and refine market concepts.
Leisure Products, Japan. Worked on backpacks and travel accessories.
Leeds Metropolitan University, Department of Leisure and Sports Sciences. I collaborated in pioneering research by Ray Lloyd into effect of load placement on posture, stability, fit and comfort and physiological parameters including heart rate, O2 consumption, tidal volume, gait patterns, pain and discomfort in different parts of the body. Research results demonstrated that a naturally balanced load carrying system significantly reduced forward lean, energy expenditure, fatigue and discomfort.
Craghoppers, UK. Developed a range of backpacks for the UK market around my core principles of natural balance, posture, movement and shaping. Introduced on the market late 1998 to much acclaim. In the first 18 months these models were on the market, they received 6 best buys in the UK outdoor magazine test reports and many recommendations.
Designed stage set for S-Club TV, London Weekend Television.
Design Council Millenium Award for Craghoppers rucksacks—one of six British products displayed in the Millenium Dome, representing the best of “British” creativity and innovation.
As a freelance designer, I had been unable to get an outside company to licence my Balance Pack designs in their completeness. This is because the designs were so fundamentally different that they made the current pack offerings of any company obsolete. No company could take the risk of such a big step forward and embrace a load carrying system which looked fundamentally different, even if it was far superior.
When I returned to NZ with my partner Devi, we set up a company to the design and manufacture products under our own label, incorporating and integrating all the biomechanical core principles that I had worked on for many years. In February 2002, we were a finalist in the DuPont Brand New Award for my ultra-lite Natural Balance Balance Pack. The prize was a free booth at the ISPO trade show in Munich. Our presence at the show, especially in the prestigious Brand New Award Hall, launched the brand and attracted several distributors for Europe.
The transition from a simple freelance design business to a successful international brand involving product development, manufacturing, marketing and distribution has been challenging. Without the wonderful support, enthusiasm and organising skills of my partner, Devi, it would not have been possible.
Introduced our inaugural range of 6 packs including Peak Aspiration, Effortless Rhythm, Essential Rapport (now called Load Limo) and Natural Balance. Compact, Sport, Expedition and Dry Balance Pockets were an integrated part of the range. Key features included U-Flow, Auto-mould shoulder straps , Hip-Surround Load Distribution and Dri-liners. 2003
Introduced 2 new models Liquid Agility and Featherlite Freedom. Liquid Agility incorporated a simplified U-Flow system ideal for daypacks. Featherlite Freedom was a smaller and simpler version of the award winning Natural Balance.
Curved Load Transfer Tubes were introduced on our largest models to create the Multi-Flow hipbelt movement system. The hips could rotate and rock, you could bend forward, and you could twist your hips relative to your shoulders. At the same time weight the hip surround load transfer system was not compromised: some of the pack weight was transferred forwards to the front of the hipbelt even during dynamic movement. 2006
Introduced 2 new models Natural Exhilaration and Marathon Magic. Our models were refocused into 2 distinct ranges, Stronglites and Ultralites. Natural Exhilaration added a tough top-opening fully waterproof daypack to the Stronglite range. Marathon Magic added a fluid performance daypack to the Ultralite range.
Developed with Marcel Hagener, a top NZ adventure racer, the key was to have a pack which moulded to your back like a limpet, no matter how tightly it was stuffed, and whether your back was straight when running or curved when cycling; which allowed amazing freedom of movement, and which enabled you to access energy bars with one hand when cycling. To achieve these requirements we developed the Omni-Flow movement system, interlinking the front shoulder and chest straps into continuous loop on each side of the body, and connecting them by an ingenious Conus clip. 2008
Introduced Guiding Light, a mid-volume Stronglite model, filling the volume gap between Peak Aspiration and Effortless Rhythm. This was a result of collaboration with NZ climbing guide Milo Gilmour and incorporated an innovative rope door behind the head to access and stow a climbing rope without taking the pack off. Balance Gear Racks were also introduced as a way to take the weight of climbing hardware off your shoulders and put it onto the front of your hips when climbing without the Balance Pockets. We also introduced 2 tent models, Pacer 1 and Pacer 2, lightweight 4 season tents designed to use trekking Poles as part of their main support structure, to reduce weight and increase wind capability.
- Robert Jarvis wins the Atacama Desert Crossing race using Marathon Magic.
- Sam Salwei and Jason Magness from Yoga Slackers snow kite across the state of North Dakota, USA in the "To Cross the Moon" expedition. Aarn Balance Packs allowed gear access at speed with the kites flying. This achievement would have been far more difficult with conventional packs.
Mountain Magic introduced. This provided a fully waterproof top opening ultralite Balance Pack, large enough for lightweight 3-4 day trips. It utilised the successful Omni-flow movement system developed for the Marathon Magics, large volume Balance Pockets and a mid-volume pack body making a naturally balanced load easy to achieve.
Dri-liners were also introduced on Sport and Expedition Balance Pockets. From the request of professional photographer, Rebecca Thompson, who found that our Balance Pocket system solved a long term problem of hers hiking with camera gear, we developed our first multi-compartment Balance Pockets.
Professional Photo Balance Pockets introduced. These allowed photographers using large bodied professional SLRs to experience the proven advantages of our Photo Balance Pocket system.
- Professors Ray Lloyd and Carlton Cooke publish a new paper comparing Balance Packs and backpacks showing that our movement systems as well as our counter balance systems are an important component of the superior load carrying efficiency of our balance packs compared to backpacks.
Liquid Agility redesigned to be far more versatile, optimising it for snow sports and cycling as well as walking and travel . Perimeter wire frames introduced on Featherlite Freedom, Effortless Rhythm, Load Limo, and Balance Pockets, reducing weights, increasing strength and improving back shaping.
New On-Adjust backlength adjustment buckle designed and introduced. This buckle allows users to lengthen or shorten the backlength without taking the pack off. 2014
Balance Bags developed to fit on any brand of pack. Posture Perfect Balance Bags provide an excellent carry-on solution for travellers using any brand of backpack, and represent the first real design solution to back related back injury in school children. Universal Balance Bags allow you to see your feet as you walk in rough country providing a counter balance system for owners of other brands of packs. Balance Bags quickly attach to your pack after you have put it on and are instantly removable before taking the pack off. 2015
Won the Outdoor Gold Award at the Outdoor show in Friedrichschafen, Germany, for outstanding pack design with the new Natural Balance pack. 2017
Mid to large volume packs: Alloy perimeter frames introduced to reduce weight and improve stiffness. All frame, movement and Balance Pocket connection systems refined for increased simplicity and durability.
Camera Balance Bags introduced for photographers which can be used with any brand of pack. 2 climbers summit Everest on seperate expeditions using our Balance Packs. 2018
- Introduce new Minilite range of small daypacks.
- Introduce large hybrid travel/ trek pack, Earth Glider, with a class leading weight/ durability/ volume ratio and a highly water resistant internal liner.
- Introduce the new Quadro hipbelt buckle:
- Spreads the load over a large area of the tummy, substantially increasing tummy comfort and improving digestion.
- High strength, yet slim and light-weight.
- Easy to tighten and loosen the hipbelt.
- Fast and simple center lift release.
- Short length allows longer adjustment range and allows S size hipbelts to fit smaller waists.
- Can be set up with a 2:1 or 1:1 tensioning web system on the hipbelt. We use 2:1 tensioning on our large packs carrying heavier loads, and 1:1 on our daypacks.
- Simplifies our hipbelts: 1 buckle replaces 4 loops, 4 connecting webs and previous center buckle.
- Center slots for attaching new Roo Pouches (small hipbelt pockets) to our daypacks when balance pockets not used.
