The BFG (Big Friendly Giant) is the rucksack that committed outdoorspeople’s dreams are made of. It has a cavern of space, clever features, and our EXACT FIT® HD (Heavy Duty) harness. The WATERLOC® canvas body is reinforced with Cordura® nylon, the floating lid expands capacity and the side zip on the large front pocket gives easy access. It’s got a plethora of attachment options, a dedicated snow-shovel pocket and dual haul loops so it’s ready to leap into the wilderness, with add-ons for versatility.

The EXACT FIT HD is the only harness in Australia designed to carry seriously heavy loads, with fits for both men and women. Built to carry loads from 15 kilograms to whatever your knees can handle, it’s endorsed by the CPAA (Chiropractors’ Association of Australasia). The EXACT FIT HD uses a higher-density closed-cell foam lumbar pad, a thicker hipbelt that stays true without distorting or compressing, and an additional foam layer on the shoulder straps. This is the choice for photographers, hunters, search & rescue and professional outdoor people.


A good harness is the foundation of every rucksack: when you load up and head off you’ll agree! Our laminated three-layer foam delivers solid support, plush comfort and a breathable contact area, with protective treatment against bacteria and rot. Our hardened aluminium frames are hand-bent, strong and light for efficiently transferring load to the lumbar pad, with channelling to increase rigidity. The double-back hipbelt contours to your body, providing support and easy fit.


We’ve combined practical understanding of bushwalking and clever design to maximise ventilation and manage moisture. There are three essential contact areas on our harnesses – both shoulders and the lower lumbar – to allow healthy carrying. Air mesh lets air flow through harness foams, while space around the spine increases natural ventilation. The secure fit allows uninhibited movement of non-contact areas, improving harness comfort when walking and scrambling. Don’t sweat it.


Made in Australia specifically for ONE PLANET, our WATERLOC canvas (390 gsm) is tightly woven and core spun, constructed from a polyester thread wrapped in cotton. The polyester core gives strength, while the cotton wrap expands when moist, providing superior water resistance. Once woven into fabric, it’s impregnated with rot inhibitors and waterproofing agents. The seams of our WATERLOC canvas bags are also bound with four-fold, 227-gsm canvas binding for reliable weatherproofing.


The floating lid and double-layered throat are designs born of experience. The lid is attached with straps, allowing extension to give 5-10 litres of extra capacity when needed: for water runs, helping mates or the start of a long multi-day trip. Functionality and comfort combine: cinch the internal compression-strap tight to create room for a broad-brimmed hat. There is also an externally-accessed pocket with key clip and a discrete internal pocket.


This functional design is born from experience. Designed to ensure complete pocket access when technical gear is attached, the large side-opening front pocket allows for versatile packing and effective organisation of equipment. The water-resistant #8 zip is positioned and straight-stitched to improve longevity and ease-of-closure, while the storm shield is shaped to close, protecting from the elements. Neat and streamlined, this pocket design enhances useability in every season.


We’ve got this game stitched up! Quality threads, twin needles, bar tacks for reinforcement and strength. Non-crack nylon buckles that bend rather than break. Durable, chunky YKK zips. The water-resistant webbing used on load-carrying straps means you won’t be given the slip. We consider every detail, creating big differences in use.


Water is critical, and never far from a bushwalkers’ mind. Our generously-cut bottle pockets are low and handy, making water accessible and putting weight close to your back for ergonomic load carrying. Perfect for bottles of all sizes, they also have a drain hole, preventing your pockets becoming buckets when it’s raining cats and dogs.


We keep it pretty simple. We take what we’ve learnt over the last 40 years and use it to make the best gear we can for antipodean adventures. ONE PLANET is more than a name: it’s a commitment to making products the right way, from fabric to construction. All rucksack design is done and manufacturing happens in our Melbourne factory.
