"2XU® Transition Backpack: The 2XU® Transition Backpack is a unisex triathlon backpack designed to handle the organizational demands of race day and multi-sport training. With 35L of capacity, it gives you enough room to carry gear across swim, bike, and run disciplines without needing multiple bags. The ultra-durable shell holds up under repeated use, while the molded ergonomic back panel distributes load evenly so the pack stays comfortable during transitions or commutes to the venue.Storage is thoughtfully organized throughout. A quick side-access laptop compartment keeps tech gear reachable without unpacking the main compartment, while multiple zipped organizer pockets help separate gear by category. Side water bottle holders keep hydration accessible on the go, and a waterproof pouch protects items that need to stay dry. External helmet attachments handle bulky gear that won't fit inside, and the chest strap with built-in whistle adds a practical safety feature for outdoor use. Adjustable padded shoulder straps dial in the fit across different body types, making this backpack a functional choice for triathletes who need reliable gear management from training through race day.Why Our Fit Experts Love It""I packed this for a sprint triathlon and appreciated how the side-access laptop compartment kept my post-race gear separate from my kit.
