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.

Tom joined the Cyclingnews team in late 2022 as a tech writer. Despite having a degree in English Literature he has spent his entire working life in the cycling industry in one form or another. He has over 10 years of experience as a qualified mechanic, with the last five years before joining Cyclingnews being spent running an independent workshop. This means he is just as happy tinkering away in the garage as he is out on the road bike, and he isn’t afraid to pull a bike apart or get hands-on with it when testing to really see what it’s made of. 

He has ridden and raced bikes from an early age up to a national level on the road and track, and has ridden and competed in most disciplines. He has a keen eye for pro-team tech and enjoys spotting new or interesting components in the wild. During his time at Cyclingnews, Tom has already interviewed some of the sport's biggest names including Mathieu van der Poel, Tadej Pogačar and Alberto Contador. He's also covered various launches from brands such as Pinarello, Ridley, Specialized and more, tackled the Roubaix Challenge sportive aboard his own rim-brake Cannondale SuperSix Evo, tested over 20 aero helmets in the wind tunnel, and has created helpful in-depth buying advice relating to countless categories from torque wrenches to winter clothing.
