Zone3 Transition Backpack  Zone3 has paid immense detail to the construction and layout of their Transition Backpack in order to make it the most durable and fit-for-purpose bag possible. Three main compartments perform key roles in storing all of your gear for race day and they allow you to properly organise yourself for each transition. Each compartment has been cleverly designed to be accessed from a different direction to help maximise space and functionality. The bottom compartment has a 100% waterproof lining with thermo-bonded seams making it perfect for storing your wetsuit tri suit or other small items from the swim leg of your race. Zone3 has engineered the middle pocket to accommodate the small essentials that you need for your race. A zipped mesh pocket is perfect for storing your goggles, swim cap and energy food and the removable PVC wallets are great for valuable items. The main cavity is designed for storing your shoes and clothes and two outer pockets fit drinks bottles. Inside the top compartment, Zone3 have spared no expense with a soft mesh lining and fleece-lined pocket for your phone or MP3 player. This pocket is ideal for items you need to access regularly like your passport, race number and wallet. The main cavity of the top section is designed to store your helmet. On the outside of the bag, reflective piping increases visibility and a padded back panel improves ergonomic comfort and breathability. Chest straps add support, which is especially handy if the bag is fully loaded and heavy, while the top carry handle makes picking the bag up easy.
