Shorts/Bottoms

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

Typically, our women's garments are designed from the ground up for women. However, the Free Aero 4 W Bibshort is designed from the ground up for racing. That specific goal leads us to a somewhat minimalist construction, but one that is made for aerodynamics and also comfort, since racing requires long hours in the saddle, both in training and on race day, resulting in one of our most comfortable shorts as well. The Free Aero 4 W Bibshort represents a significant evolution from last year's model, our best-selling short ever. 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 Sky 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 new Free Aero 4 W Bibshort also receives the updated Progetto X2 Air Seamless seat pad featuring the softest surface fabric you've ever felt in a seat pad. Product Features - Vortex dimpled fabric on legs for aero performance - Forza fabric on inner legs with 38% Lycra content for perfect fit - Stripe mesh engineered lie-flat bib strap construction keeps you cool - Giro4 leg gripper elastic for better grip distributed over larger area - Doppio V construction in front for increased comfort - Flat-lock stitching - Progetto X2 Air Seamless Donna women's-specific seat pad - 15°-35°C / 59°-95°F - Weight: 156g

The performance tight with the right weight for most winter riding, with a focus on comfort, stretch, and protection. - Nano Flex 3G fabric from waist to knee for soft warmth with maximum stretch and water repellency - Nano Flex stretch woven fabric with brushed fleece inside at lower leg for splash protection on wet roads - Stretchy bottom of leg with raw-cut edge means ankle zipper is not necessary - Minimalist bib straps, as found on the Free Aero RC Bibshort, don't add extra bulk - Rear pocket at bottom of bib straps - Reflective tabs on back of legs - Progetto X2 Air Seamless seat pad for long hours in the saddle

Meticulous Evolution The Free Aero Race 4 Bibshort is our top race short, which also means that it's insanely comfortable even if you never pin on a number. The original Free Aero Race Bibshort was first introduced over a decade ago and has logged literally millions of kilometers under the backsides of our sponsored pro riders and has been the best-selling short both in the Castelli retail collection and in our Servizio Corse custom program. Over this time the short has undergone numerous updates and improvements in the never-ending quest to create the best short we can make. While the basic concept of a minimalist workhorse pro-level comfortable race short remains, every single fabric, component, stitch and construction method has been updated and improved over time. The fourth major generation of the short features the updated Progetto X2 Air Seamless seat pad. This pad separates a soft, stretchy skin care layer that moves with your body from a generously padded cushioning layer that replicates the form of your saddle. Eight-hour rides are no problem. Of course the fabrics are premium, made to our specifications by Italy's best fabric suppliers. The Forza fabric on the inner leg features 38% Lycra content for perfect fit, while the Vortex fabric on the side panels is dimpled for aerodynamics. And it's held in place by the latest iteration of our seamless flat Giro leg gripper. - 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 - 15°-35°C / 59°-95°F - Weight: 172g

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. The revised Free Aero Race 4 Short 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 - 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

This is our warmest tight for cold riding conditions. Our warmest GORE-TEX INFINIUM™ WINDSTOPPER fabric covers the entire front of the tight to keep the cold wind out. We use water-repellent Nano Flex 3G on the bum and the back of the lower legs for splash protection from wet roads, while Thermoflex on the back of the thighs gives extra stretch for the renowned Castelli fit. This is now the most comfortable wind tight we've ever made. We’ve kept the bib straps to a minimum so that you can layer your upper body exactly as you wish, without an unwanted thermal layer covering your stomach. With more of us riding at night, we've placed large reflective inserts on both the front and back of the legs, where the up-and-down pedaling motion grabs the attention of approaching motorists. - Full GORE-TEX INFINIUM™ WINDSTOPPER X-Fast front for total wind protection - Nano Flex G3 on seat and lower back leg for splash protection from wet roads - Thermoflex back of thigh for extra warmth and stretch - Mesh bibs don't hold moisture - KISS Air2 Donna seat pad gives great cushioning without excessive bulk - High-visibility reflective stripes above knee in front and above calf on back - Ankle zips for easy on/off

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

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

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

We made this tight for serious winter riding. That means keeping you protected and comfortable in the widest possible range of conditions. Easy to say, but harder to actually do. The main part of the tight uses our Nano Flex 3G fabric, the third generation of our proprietary 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, for luxurious comfort with the best protection on the market. We add Nano Flex Xtra Dry panels to provide a bit more wind protection and warmth in the front and over the thighs. 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 so you hardly notice them.

Our Sorpasso tight is our workhorse performance tight for the cyclist who rides seriously right through the winter months. With the Sorpasso Wind we add a GORE-TEX INFINIUM WINDSTOPPER fleece-backed panel covering your most sensitive parts as well as your thigh muscles to keep them at ideal operating temperature. While many wind tights will sacrifice fit or comfort or breathability for that wind protection, the two-way stretch of this fabric combined with careful patterning makes for minimal compromise and maximum comfort. Everything else on this tight represents our commitment to performance and comfort: the non-windproof parts are in Nano Flex 3G and Nano Flex Xtra Dry to provide stretch, warmth, breathability, and our proprietary water-repellent finish. They're the best tights fabrics we've developed to date. The seat pad is our top-of-the-line Progetto X2 Air for comfort on long rides, and the bib construction is designed for comfort as well. Large reflective panels at the back of the ankle provide moving reflectivity that is more noticeable to approaching cars. This is the tight for you if subfreezing temperatures aren't going to hold you back. - Nano Flex 3G fabric for our best mix of warmth, stretchy compression, softness and water repellency - GORE-TEX INFINIUM WINDSTOPPER X-Fast fleece-backed fabric panel on the upper front and thighs for extra warmth - Nano Flex 3G back panel 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
