Castelli has launched a new cycling jersey with a specific pocket for a hydration bladder. The Unlimited Pro jersey is designed for 'multisurface racing' and will accommodate a 1.5-litre fluid bladder in a pocket on the back panel of the jersey, which also features loops for the bladder hose.

Gravel and Ultra distance racers often wear small Camelbak-style backpacks with a hydration bladder which allows them to carry extra fluids with them in between aid stations or feed zones. The Unlimited Pro jersey looks to have a performance-focused fit and features dimpled aero sleeves, but will mean riders can do away with a backpack and simply carry a fluid bladder in the jersey's built-in pocket. This should save some weight, as well as being cooler and more aerodynamic.
