Looking for the best hydration backpack to keep you going on your next outdoor adventure? Whether you’re a runner, mountain biker, or weekend hiker, staying hydrated is essential—and sometimes a water bottle just doesn’t cut it. That’s where hydration packs come in.
The team at Thule has put together this simple guide to help you choose the perfect hydration pack for your activity, so you can stay focused on the trail, not your thirst.
What Is a Hydration Pack?
A hydration pack is a specially designed backpack or hip pack that holds water and allows for hands-free drinking. Most include a built-in reservoir (also called a bladder) and a hose for sipping while on the move. Some designs also accommodate standard water bottles. These packs are perfect for longer runs, hikes, and bike rides where stopping to drink isn’t ideal.
Types of Hydration Packs
Hydration Backpacks

These are ideal for athletes who need to carry more water and gear. The reservoir sits inside the pack, and a hose extends over the shoulder strap so you can drink while moving. They also include space for snacks, keys, and layers of clothing.
Best for: Trail runners, marathoners, mountain bikers, and long-distance hikers
Why choose it: Balanced weight distribution, large water capacity, and extra storage
Hydration Hip Packs

These are compact packs worn around the waist. They’re popular with mountain bikers and runners who want to reduce weight on their back and shoulders. Some hip packs use reservoirs; others have side holsters for water bottles.
Best for: Short runs, trail running, and technical MTB rides
Why choose it: Lightweight, low-profile, and better ventilation for your back
What Size Hydration Pack Should You Choose?
Choosing the right size depends on your activity and how far you’re going. Keep in mind that water adds weight, so it’s smart to carry only what you need.
- 0.5 litres: Ideal for short-distance runs or hikes
- 1 – 1.5 litres: Great for moderate runs and bike rides
- 2 – 2.5 litres: Best for long-distance efforts with limited refill options
How Do Hydration Packs Work?

Hydration Reservoirs
Most hydration packs come with a plastic reservoir and a hose, allowing you to sip without breaking stride. This setup keeps your hands free and helps you maintain momentum on the move.
Magnetic Hose System (Retrakt™)
Thule’s exclusive Retrakt™ System uses a magnetic clip to keep the drinking hose secure and out of the way after each sip—perfect for runners and riders who don’t want distractions.
Water Bottle Options
Some hydration packs, especially hip packs, are designed to carry water bottles instead of a reservoir. These offer fast access and are easy to clean, making them a favourite for shorter activities.
