    What makes the ZONE3 Transition Bag different?

    Boasting a 40-litre capacity and an innovative design that makes it much more than just a bag to carry kit in. The transition bag has been cleverly designed so that each compartment is accessed independently to help maximise space and functionality.
    We found that most backpacks on the market were not sturdy enough to remain standing unless the bottom section was being used or there were no compartments. In our unique design we have tailored the inner linings between each compartment so they can naturally flow into the compartment below, ensuring it can stand strong regardless of how full or empty it is.

    BOTTOM WETSUIT COMPARTMENT: 

    With a fully waterproof & flexible inner lining and durable outer fabric, the wetsuit storage area makes the ideal place to store your wetsuit when travelling to and from events and training. Made with some of the most advanced waterproof fabrics around, the inner lining not only makes sure the rest of the bag stays dry but also folds flat when not in use to further expand the main compartment. The outside of the compartment features a tough and durable material designed to withstand everyday wear and tear and all-weather conditions.

    • Outside: 100% waterproof and durable exterior material.
    • Inside: Expanding 100% PU coated waterproof lining material with thermo-bonded seams.
    • Suitable for a wetsuit, Tri suit and other small items.

    MAIN COMPARTMENT: 

     

    A large main compartment in the centre of the bag caters for all your tri clothing, casualwear, shoe & accessory needs. The compartment opens outwards to feature multiple contrast-lined interior pockets for easy access to accessories. This compartment also features a fully waterproof removable pouch to separate any wet or dirty items you may have or keep important documents such as race documents in before the event. The compartment has also been designed to expand into the lower wetsuit space when not in use, allowing for further expansion and storage. On the exterior of the bag, there are two large mesh bottle holders, perfect for sports bottles of any size to keep you hydrated throughout your training & racing.

     

    • Inside: Zipped mesh pocket for goggles and accessories
    • Inside: 100% waterproof removable PVC wallets for small valuable items.
    • Inside: Back of flap features mesh pocket for race numbers and information.
    • Outside: Two large, soft mesh pockets perfect for drinks bottles.
    • Suitable for shoes, clothing, towels, accessories, drinks.

     

    TOP COMPARTMENT: 

     

    A zipped cycle pocket at the top of the bag is the ideal storage place for your cycle helmet and shoes, always keeping them safe and easily accessible. The premium mesh inner lining also ensures your kit stays in pristine condition, while the built-in phone pouch gives you hands-free access to your music throughout your travels. The rear of the bag features ultra-comfortable padded & adjustable shoulder straps as well as a padded back panel to ensure maximum comfort whether you are travelling 5 miles or 5000.

FAQ

Questions and answers relating to Zone3 Transition Backpack

What is the main benefit of using a specific transition backpack?

Answer

The main benefit is speed and organisation in T1 and T2. This backpack features dedicated, labeled compartments that allow you to organise gear logically (swim, bike, run), ensuring you find exactly what you need without chaos when seconds count.

What is the capacity of the bag, and is it suitable for a long-course race?

Answer

The bag typically offers a generous capacity of around 40 litres. This size is ample for storing all required gear, nutrition, and apparel for any distance, from a Sprint to a full Ironman.

How does the bag handle wet wetsuits and gear?

Answer

It features a separate, waterproof compartment (often ventilated) designed specifically for storing your wet wetsuit, tri-suit, or towel immediately after the swim. This prevents moisture from reaching and soaking your dry bike and run gear.

Does the bag have a separate space for a helmet?

Answer

Yes. The backpack includes a dedicated, protective compartment (often fleece-lined or rigid) designed to safely store and protect your cycling helmet from damage during transport to the race venue.

Can I attach a water bottle to the outside of the bag?

Answer

Yes. Most transition bags include mesh pockets or external straps designed to securely hold large water bottles or specialised triathlon hydration systems for easy access.
