The 2XU Transition Bag is a considerable amount larger than the 2XU backpack and the size of the bag roughly 60cm (height) x 35cm (width) x 20cm (depth). The bag is the ultimate training bag for any triathlete but is not limited to these customers and could also be used by many consumers as an everyday gym bag or large travel backpack. The bag is extremely well made, durable and looks fantastic.
