Guide to Buying Running Hydration Packs
Running hydration packs are designed to help you stay hydrated during runs without needing to stop or carry bottles by hand. By combining lightweight construction with built-in hydration systems, they allow you to drink while moving, maintain rhythm, and focus on your performance.
Running Hydration Backpack
Our running hydration backpacks are simple and easy to use, a perfect tool for long-distance and marathon runners who require refreshment on the move. If you’re planning to wear a running hydration pack on your next marathon or big race, you should wear it during training so that your body adjusts. Our running hydration packs will keep you supplied to the finish line. Choose from a variety of different colours and styles.
Running Bags
Here at Trespass, you’ll find a range of running bags and vests that are lightweight and supportive. A running bag should fit close to the body to avoid friction so that you can perform your best stride every time. Find a running backpack that has enough space to store your energy gels and snacks. If you don’t require a full-sized bag - our running belts and running bum bags are ideal for shorter runs when you only need to carry your keys and phone.
Running hydration packs are designed around fit, water capacity, and storage needs to suit different running styles and distances.
- Running hydration vests: Low-profile designs that sit close to the body, offering a snug fit and minimal bounce. These are ideal for road running, trail running, and races where stability matters most.
- Hydration backpacks: Slightly larger packs with rear compartments, suitable for longer runs or mixed activities where you need to carry extra gear, layers, or nutrition.
- Hydration belts: Minimalist alternatives that carry small bottles around the waist. Best suited to shorter runs or runners who prefer very lightweight solutions.
- Multi-use run packs: Versatile options that balance hydration capacity and storage, working well for running, hiking, and general outdoor use.
Each style allows runners to carry water in a way that suits their distance, pace, and terrain.
Well-designed details improve usability and comfort while running.
- Integrated hydration bladder or compatibility with soft flasks.
- Front pockets for easy access to nutrition, phone, or keys.
- Zip pockets and zippered pockets for securing valuables.
- Stretch pockets for storing gloves, gels, or extra layers.
- Adjustable shoulder straps and sternum straps for a secure fit.
- Rear compartment or rear storage for additional gear.
- Reflective details to improve visibility in low-light conditions.
Together, these features help create a comfortable fit with minimal bounce and easy access while moving.
Different running styles place different demands on hydration packs.
- Road running: Lightweight running hydration vests with a snug fit, front pockets, and soft flasks for easy access.
- Trail running: Running hydration packs with secure fit, breathable mesh, stretch pockets, and pole attachment options for trekking poles.
- Long-distance and endurance running: Larger packs with hydration bladders, rear storage, and enough space for extra gear and nutrition.
- Summer running: Highly breathable packs with airflow panels and easy-access hydration to help you stay hydrated in warm conditions.
Choosing the right style ensures comfort, stability, and efficient hydration across different running environments.

How to choose the best running backpack?
- When choosing a running backpack, the options are endless! Our top piece of advice is to consider why you need it? If it’s a marathon, you’ll want a minimalist running hydration vest to keep the weight as light as possible, whereas if you’re running on your daily commute, you’ll want something with enough space to carry your essentials. The best running bags should feel lightweight and supportive. Look for a bag that has straps for your shoulder, chest, and waist so that you can run comfortably.
