Description
Orca Transition Backpack: One bag for everything triathlon
Triathlon means a lot of kit: wetsuit, helmet, shoes, nutrition, a towel and a change of clothes. The Orca Transition Backpack gives each item its own place, so packing is quicker and you’re less likely to forget something.
Wet and dry kit kept apart
A separate compartment underneath holds your wetsuit, trisuit and other wet gear, so it stays away from your clothes and valuables after the swim. Your helmet goes in its own integrated compartment, and several pockets and protected sections keep smaller items organised and easy to find.
Expands when you need it
When race day takes more kit than a normal session, an expansion zip gives you 15cm of extra depth. The flat base lets the bag stand upright on its own, so it’s easy to unpack in transition or at the poolside.
Comfortable to carry
Wide padded straps spread the load. The breathable back panel holds the bag slightly away from your back, so you stay cooler on the walk to registration or the ride home.
