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

It Just Works Right Castelli has innovation in our DNA, and we've brought you most innovations in cycling shorts over the years: the first Lycra shorts on the market, the first synthetic seat pads, the first anatomical seat pads, the first minimalist and flat bib straps, and the first flat leg grippers. All these have become industry standards, and we keep pushing and innovating in our high-end shorts. The Entrata short is where we bring all that knowledge and experience into a short that just plain works. The fabric is just the right weight with just the right stretch and with a matte finish that looks just right. The KISS Air2 seat pad is just right, as is the GIRO3 leg gripper. And the short fits just right because we obsess over the fit of every short we make. We wanted this short to be just right for many years to come, so we stitch on the logos and stitch in the reflective panels on the back. There are no logos to peel off, and everything is stitched down securely. This short gives you every reason to step up to Castelli. - KISS Air2 seat pad for all-day comfort - Pro Dry matte Lycra for good compression and moisture management - 8-panel construction for perfect fit - Rear reflective panels on lower leg - GIRO3 engineered flat leg band - Mesh bib straps for comfort and breathability - 15°-35°C / 59°-95°F - Weight: 175g

For 2019 we've made some dramatic changes. Not because Team Ineos or you were asking for it, but because we've been riding in it a ton and thinking constantly about how we could make it better. There's a new leg gripper that still features a lie-flat raw-cut edge but now has vertical silicone stripes to keep it in place without restricting stretch. The new fabric allows for better print quality for your custom team production, the same as Team Ineos will use in 2019. We've updated the seams to improve the fit and make the short look even better on the body. We've re-engineered the bib straps with new fabrics and construction so they stay cooler, lie flatter and are more durable. The revised Free 3 Aero Race Bibshort also receives the updated Progetto X2 Air seamless seat pad featuring the softest surface fabric you've ever felt in a seat pad. You'll be glad we ignore the old saying, If it ain't broke, don't fix it. - Vortex dimpled fabric on legs for aero performance - Forza fabric on inner legs with 38% Lycra content for perfect fit - Stripe mesh engineered minimalist bib construction keeps you cool - Giro4 leg gripper elastic for better grip distributed over larger area - Doppio V construction in front for increased support and comfort - Flat-lock stitching - Progetto X2 Air Seamless seat pad

The name of this tight, Sorpasso, means "overtaking" in Italian. That's what we've tried to do with this tight, to make it a bit faster, better, more comfortable. It's made to be technical equipment for riding in the widest range of winter conditions. The main part of the tight uses our Nano Flex 3G fabric, the third generation of our nanotechnology fabric treatment that adds a high level of water repellency without affecting the breathability, stretch or warmth of the fabric. You get a highly stretchy, compressive fit that moves with you, focusing on warmth and comfort. But then we add a few panels of the Nano Flex Xtra Dry fabric to provide a bit more wind protection and warmth in the front panel and over the thighs, and in the back for extra protection from road spray. It's not only about the fabrics: anatomical patterning gives a bend at the knee and the hip, while the seamless bib straps lie flat and securely keep everything in place. Our generously padded Progetto X2 Air seamless seat pad makes long rides more comfortable, and you have multiple reflective panels to keep you visible. We've designed this as the go-to tight for a full winter's riding. - Nano Flex 3G fabric for our best mix of warmth, stretchy compression, softness and water repellency - Nano Flex Xtra Dry fabric panel on upper front and thighs for extra warmth, and on back to protect from road spray - Anatomic cut to hips and knee - Reflective inserts for maximum visibility from behind - Lie-flat elastic bib straps - YKK Camlock zippers at ankles

Our top-selling Sorpasso Bibtight is also available in a 3/4-length version for those cool but not quite cold rides or for those of you who just like the feeling of not covering your lower leg. The fabrics are exceptionally soft, stretchy, and warm, with our Nano Flex 3G covering most of the body and panels of Nano Flex Xtra Dry covering the front, thighs, and center back. We've added reflective panels for safety and given it the most comfortable seat pad and bib strap construction we can. - Nano Flex 3G fabric for our best mix of warmth, stretchy compression, softness and water repellency - Nano Flex Xtra Dry fabric panel on upper front and thighs for extra warmth, and on back to protect from road spray - Anatomic cut to hips and knee - Lie-flat elastic bib straps
