The Styx is made for weekend getaways and multi-day expeditions. Dual access allows easy organisation, whilst the 70 litre (medium) capacity has room for comfort items. It has a separate 3D external pocket on the front, with a clean, scrub-friendly design so it won’t catch on trees, rocks or trailers. It has the comfort of the famous EXACT FIT harness, and the durability and water resistance of a WATERLOC® canvas body and double base. Gear attachment options, add-ons and hydration compatibility keep it personal.

One Planet Gear Attachment


The EXACT FIT harness is the go-to for multi-day bushwalking, comfortably carrying ten to 30 kilograms. Endorsed by the Australian Chiropractic Association, it’s available in four standard sizes for males and four standard sizes for females, allowing for an exact fit for your physique. Grippy airmesh improves both ventilation and pack to body adherence for enjoyable bushwalking. An industry benchmark, it is designed for comfortable and healthy load carrying, and is the ideal choice for on- and off-track adventures.


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


The EXACT FIT Mid is a lightweight harness that offers serious support, with a Goldilocks carrying capability of between 5 and 20 kilograms. It’s available in fits for both males and females across three sizes, with interchangeable hipbelts and shoulder straps allowing a personalised fit. Grippy air mesh improves both ventilation and pack-to-body adherence for enjoyable bushwalking. The EXACT FIT Mid is the harness of choice for overnight trips and lightweight adventures.


Made in Australia specifically for ONE PLANET, the 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 ONE PLANET 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.


There are advantages of both top-loading and bottom-access packs: the floating internal floor gives you the best of both. Made from waterproof fabric, the internal floor follows the form of the rucksack. When top loading, this floor lies flat, out of the way; when packing the bottom compartment, it is a strong, flexible divider. No more under-filled gaps, no more fiddly dividers.


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. ONE PLANET consider every detail, creating big differences in use.


Water is critical, and never far from a bushwalkers’ mind. The 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.


ONE PLANET keep it pretty simple. They take what they’ve learnt over the last 40 years and use it to make the best gear they 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 their Melbourne factory.
