A hydration pack solves a specific problem: how to carry enough water for a long run, hike, or ride without stopping to get a bottle out of your bag. The reservoir sits inside the pack, a drinking tube runs over your shoulder, and you drink without breaking stride or stopping. For activities where hydration matters and stopping is inconvenient, it's a genuinely better solution than a water bottle.

Types of Hydration Packs
Running Hydration Packs
Minimal, close-fitting packs designed to stay stable at running pace. Typically 5–12L capacity with a 1.5–2L reservoir. The fit is snug to prevent bounce — look for adjustable sternum straps and a back panel that sits close to the body. CamelBak's Circuit and Rogue series are the benchmark for trail running hydration packs.
Hiking Hydration Packs
Larger capacity (15–30L) with a 2–3L reservoir and room for food, layers, and gear alongside the water. A proper back system with a hip belt is important at this size — the pack needs to carry comfortably for hours. Tatonka's hydration-compatible hiking packs work with standard 3L reservoirs. Browse the full hiking backpacks range for packs with hydration compatibility.
Cycling Hydration Packs
Aerodynamic profile, helmet-compatible back panel, and a drinking tube routed for easy access while riding. Typically 10–20L with a 2–3L reservoir. CamelBak's MULE and Lobo series are the most popular cycling hydration packs, with a low centre of gravity and stable fit at speed.
Standalone Hydration Reservoirs
Replacement reservoirs and bladders for existing packs. CamelBak's Crux reservoir is the most widely compatible option — fits most hydration-compatible packs from any brand. Available in 1.5L, 2L, and 3L.

Frequently Asked Questions
How do I clean a hydration reservoir?
Rinse with warm water after every use. For a thorough clean, use a hydration cleaning kit (brush for the reservoir, brush for the tube) with a mild cleaning tablet or diluted white vinegar. Dry fully before storing — a damp reservoir grows mould quickly. Store with the reservoir open or inside out to allow airflow.
Are CamelBak reservoirs compatible with other packs?
CamelBak reservoirs fit most hydration-compatible packs from other brands, provided the pack has a standard reservoir sleeve and tube port. The Crux reservoir's universal design makes it the most widely compatible option. Check your pack's reservoir sleeve dimensions before buying a replacement.
How much water should I carry for a day hike?
The general recommendation is 500ml per hour of hiking in moderate conditions, more in heat or at altitude. For a 6-hour day hike in Australian summer conditions, carry at least 3L. A 3L reservoir plus a reusable water bottle gives you 4–5L total — adequate for most full-day hikes with no water sources on the trail.
Do I need a hydration pack or just a water bottle?
For activities under 90 minutes where you stop regularly, a reusable water bottle is simpler and lighter. For trail running, long hikes, and cycling where stopping to drink is inconvenient or you need more than 1L, a hydration pack is the better choice.
