The Right Race Jersey for Speed and Comfort Some triathletes choose long sleeves for the extra speed. Some for the comfort. Some for sun protection. This jersey gives you all three. The aerodynamic speed is unmatched. It's what Castelli does best. We have a year-round testing and development program with the Norwegian Technical University in Trondheim to make our race gear the slickest around. The comfort is what comes from our expert pattern engineers and soft performance Italian fabrics. We reduce the number of seams so that there is less chafing and less to bother you when you should be concentrating on pounding out the run. Sun protection...well, you've trained untold hours for this day. We focus on speed, but we still manage to block 94% of UV rays with our back Velocity mesh fabric that doesn't compromise speed, comfort or breathability. You may want to add some sunscreen, but this fabric provides UPF 16 protection, which is a significant help. Your cotton T-shirt is probably UPF 8. Take note of the well-thought-out details: Castelli's generous two pockets lie flat but hold a lot of gear and nutrition. The SnapLock fasteners clip to Castelli shorts to prevent the top from riding up during the swim or bike. - Freedom of movement in the water, aerodynamics on the bike, comfort on the run - Velocity Rev2 aero fabric on front-facing surfaces - UPF 16 Velocity mesh back blocks 94% of UV light with generous breathability - 2 rear pockets lie flat and prevent nutrition from bouncing around - GIRO3 flat gripper elastic lies flat on lower back - SnapLock fastener at lower back to clip to Free Tri Short to prevent riding up during swim or bike leg - YKK Camlock zipper - Elbow-length sleeves for maximum aerodynamics

A tri top has never been this comfortably fast Tri fashion (and the wind tunnel) have pushed toward short-sleeve tops, but we think there's still a place for the traditional sleeveless top. It's more comfortable on the run and cooler in hot weather. . . And maybe you're just a traditionalist. We've packed this top full of features: the front fabric comes straight from our Tour de France winning aero race jersey, and the back fabric offers maximum breathability. The top has two generous pockets for whatever you need to carry. It has snaplock fastners that clip on to Castelli shorts to prevent the top from riding up during the swim and to keep coverage of the lower back on the bike-then you unclip for added comfort during the run. The YKK zipper makes adjusting the ventilation easier than ever. Finally, we've taken extra care around the armhole to make it lie flat for speed yet remain soft to prevent chafing. - Freedom of movement in the water, aerodynamics on the bike, comfort on the run - Velocity rev2 aero fabric on front-facing surfaces - UPF 16 velocity mesh back blocks 94% of UV rays, with generous breathability - 2 rear pockets lie flat and prevent nutrition from bouncing around - Giro3 flat gripper elastic lies flat on lower back
