Like the ultimate race short, only less This isn't quite a "boy short" with a very low waist and short legs, but it is a shorter short than the Castelli free 2 w tri short. It's still very much a performance race product, but just shorter in the waist by a few cm and shorter in the legs as well. - Instadry speed fabric is fast in the swim with minimal water absorption - Free construction for great anatomic fit - Kiss tri seat pad is comfortable on the bike and virtually disappears on the run - Flat-lock stitching - Pocket at center back for gel -GIRO3 leg gripper elastic for more comfort

The ultimate race short You know Castelli can make a great bike short. This one doesn't disappoint, thanks to amazing fit, the quick-drying instadry fabric that gives compressive muscle support, and the renowned kiss tri seat pad. New giro4 leg grippers hold the longer legs in place without riding up. For the swim we've made the short smoother through the water, and the back pocket will lie flat to avoid catching water. The snaplock closure clips to your Castelli top to keep it from riding up. On the run, the short basically disappears. The kiss tri seat pad is thin enough you don't really notice it. This short is so comfortable you'll be using it for training rides as well as racing. - Instadry speed fabric is fast in the swim with minimal water absorption - Free construction for great anatomic fit - Kiss tri seat pad is comfortable on the bike and virtually disappears on the run - Snaplock fastener at waist to clip jersey into place for swim and bike - Flat-lock stitching - GIRO4 leg gripper elastic for more comfort - Longer length for improved 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

A Better Short Shorts are an obsession at Castelli. They're the most vital piece of clothing and one of the hardest to get right. Even though the Prima is our entry-level short, it shows that we won't compromise anything for comfort and performance. It starts with the women's-specific KISS Air2 seat pad. Just the name gives an idea of the process of constant improvement, which started with a soft KISS pad that was improved by making it more breathable (Air) and then improved again in the latest update to use the softest-ever top fabric (2). It's ready for your next big ride indoors or out. We've updated the fabric to the new Pro Dry Soft, which has a smooth matte finish that feels cool on the skin while being very supportive and quick to dry. We wanted this short to be just right for many years to come, so little details like the reflective patches are stitched in instead of being glued on, and the GIRO3 elastic has the grip woven right into the fabric. This attention to detail — go ahead and call it an obsession — is why Castelli's entry-level short is just a better short. - KISS Air2 seat pad for all-day comfort - Pro Dry Soft matte Lycra is sleek looking and ultra-breathable - Anatomic construction for perfect fit - Rear reflective panels - GIRO3 engineered flat leg band - 15°-35°C / 59°-95°F - Weight: 160g
