Gear review: best trail running backpacks for gear storage
A trail pack should carry essential equipment without interfering with stride, balance or breathing. The best trail running backpacks for gear storage offer quick access, a secure fit and enough room for mandatory kit without becoming bulky or restrictive.
Capacity matters less than organisation. A compact 12-litre pack may suit a fast 50-kilometre race, while an ultra runner carrying insulation, food and emergency equipment may need 17–25 litres. Some races require little more than soft flasks and a shell; others demand almost a small overnight bag.
Australian conditions widen that range. The exposed sandstone and sharp singletrack around Katoomba during Ultra-Trail Australia punish poorly secured bottles and uncomfortable harnesses. Melbourne’s damp tracks, Perth’s jarraf forests and summer races across South Australia can bring heat, humidity, intense sunshine and sudden rain.
Fit should outweigh brand loyalty or advertised weight. A well-fitted, ventilated pack feels lighter than a lighter model that bounces, rolls or presses into the ribs. Useful assessment points include load transfer, access to hydration, internal organisation, durability and likely availability through Australian retailers.
A practical comparison of race-day options
These four packs cover different interpretations of a race backpack: compact and speed-focused, ultralight, highly supportive or roomier for long-distance travel. Capacities and features matter only in combination with the runner’s size, race demands and preferred pace.
| Pack | Capacity | Best suited to | Main strength | Main limitation | Indicative Australian price |
|---|---|---|---|---|---|
| Salomon Sense Trail 12 | 12 L | Fast 50–100 km races | Close fit and quick hydration access | Limited structure for bulky gear | A$180–A$280 |
| Terra Equipment Element 12 | 12 L | Technical and fast ultras | Low weight and weather resistance | Roll-top and limited organisation | A$220–A$300 |
| Osprey Zealot 25 | 25 L | Long ultras with substantial kit | Supportive load carrying | Heavier and more cumbersome | A$150–A$250 |
| Mystery Ranch In and Out 17 | 17 L | Comfort-focused long-distance running | Stable harness and useful capacity | Less nimble for short races | A$160–A$230 |
Prices fluctuate with sales, imported stock and Australian GST, so the value of a discontinued model can improve considerably through second-hand sales. The correct comparison is the complete kit on race day: a light bottle that rattles is worse than a well-balanced 15-litre load.
Choosing capacity for the distance
For a shorter trail race, start with the organiser’s mandatory equipment list. A wind shell, soft flask, phone, personal identification, basic first aid and the specified emergency garment can occupy less than eight litres. The Space Race-style Australian emphasis on moving quickly and carrying little also applies to general trail running: every unnecessary item creates friction.
Longer events add food, spare layers, more water and greater safety requirements. A 12-litre pack works when insulation is compact and food is accessed frequently. A 17–25-litre pack makes sense when carrying a bulky jacket, multiple layers or camera equipment.
Storage design can matter more than litres. Top openings suit race kit, side access helps during long descents, and internal dividers stop a bottle from crushing food. A roll-top may handle weather well, while a structured compartment can keep mud, wrappers and small tools separated. Remote Australian courses also justify an Emergency+ subscription or satellite communicator where mobile reception cannot be assumed.
Salomon Sense Trail 12: speed and compact storage
The Sense Trail 12 is the most race-oriented option here. Its close-fitting harness, stretch front pockets and provision for a reservoir or two soft flasks keep hydration within easy reach. Storage remains sufficient for compact clothing, food and mandatory safety items without giving the pack the profile of a hiking pack.
Its weaknesses appear when the load becomes bulky or the race demands prolonged descents. Limited internal structure can allow items to shift, while relatively light shoulder padding may create pressure during a hot, multi-hour event. It remains a strong choice for Australian 50–100-kilometre races where speed and compact storage outweigh carrying comfort.
Terra Equipment Element 12: minimal weight and weather resistance
The Element 12 prioritises low weight and a simple exterior. Its roll-top closure handles splashes and showers better than many conventional zippered lids, while the compact body sits cleanly against the torso. It works well for technical trail running, fast hiking and races where food and clothing can be compressed into small volumes.
Organisation is the trade-off. There are fewer places for a phone, glasses, camera or wet jacket than in a conventional hiking pack, and soft flasks may need careful positioning to avoid pressure points. In Melbourne’s wetter months or along the exposed Blue Mountains, its weather-resistant character is valuable, but it still needs a liner for sustained rain.
Osprey Zealot 25: comfort for longer ultras
The Zealot 25 accepts a substantial load without the pronounced movement associated with lighter racing packs. Its internal structure, adjustable torso and broad hip belt distribute weight across the hips and lower torso. That stability becomes useful during a 100-kilometre race carrying extra layers, several litres of water and a full emergency kit.
The volume is also its main disadvantage. Carrying 25 litres on technical singletrack is inefficient, and the pack can become warm during fast running in an Australian summer. Older models may offer strong value, but runners should inspect foam, buckles, zips and stitching because age can outweigh a low sale price.
Mystery Ranch In and Out 17: a roomier mountain pack
The In and Out 17 sits between a race pack and a lightweight mountain pack. Its structured harness, load lifters and substantial hip belt create a composed, comfortable carry when the contents include bulky weather gear or enough supplies for an extended section. The wide opening also makes it easier to locate food and spare clothing.
That extra capacity suits long ultras, mountain courses and runners who regularly carry a compulsory bivvy. It is less persuasive for a fast 50-kilometre race where carrying only a shell and flasks would be sufficient. Its shape may also feel intrusive on narrow trails, so testing with the final load is essential.
Care, value and the best choice for Australia
The strongest all-round choice for most runners is the Sense Trail 12, provided its smaller capacity matches the event. The Element 12 appeals to those seeking the lightest setup, the Zealot 25 supports heavier loads, and the In and Out 17 favours comfort over race efficiency. Personal fit should decide the result.
Australian buyers can compare stock and prices through specialist running stores such as Runner’s Edge, Trek King and Trail Runner Direct, as well as general outdoor retailers. Imported models may include GST but offer fewer replacement buckles or straps. Local availability and warranty support can therefore influence value as much as the specification sheet.
After use, dry the pack thoroughly, remove salt and sand from seams, wash the reservoir and inspect zips, foam and compression straps. Store it loosely rather than packed tightly, because prolonged compression can damage foam that supports the runner’s shoulders and waist. Replace any cracked buckle before it matters on course.
Choose one pack, load it with the exact race kit, and complete a one-hour shakedown walk on a local trail before race day.
