Castelli are renowned for pushing boundaries when it comes to cycling performance. And the Entrata VI Short Sleeve Jersey benefits from this extensive R&D, engineered with the same attention to detail as their top-end jerseys. This can be seen in the one-piece sleeves, with aero-optimized seaming, keeping you streamlined as speeds rise. Raw-cut sleeve endings also fit brilliantly, without constricting. Four-way stretch Air Mesh fabric gives a snug but comfortable fit. And it’s lightweight too, perfect for warm summer days on the bike. Castelli also adds their ProSecco treatment, ensuring sweat is dealt with quickly and efficiently. UPF 30 sun protection, filtering 97% of UV rays, also keeps you more comfortable under summer skies. Details are thoughtfully applied too. A full-length YKK® Vislon® zipper is easy to slide, a stretch panel in the centre pocket allows extra carrying space and a silicone gripper keeps the back of the jersey in place. As the sun sets, a reflective insert on the pocket keeps you more visible as you pedal homewards.
