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: 173g

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

At the leg ending we use a raw-cut edge with vertical silicone strips just like on our top-of-the-line Premio shorts to keep the leg in place without the pressure that creates the dreaded sausage effect.

The main Vortex textured fabric and the Giro4 leg gripper come straight from our top Free Aero Race 4 Bibshort, while the KISS Air2 seat pad has most of the comfort of our top seat pad but represents maximum value.

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 - SnapLock fastener at lower back to clip to Free Tri Short to prevent top from riding up during swim or bike leg - YKK® Camlock® zipper

The fabric focuses on breathability to keep you dry as well as maximum stretch.

The ideal tight for most of your winter riding, the Velocissimo is focused on comfort for riding in mild to cool conditions. We've used our Thermoflex fabric for most of the tight. It's not our warmest fabric, nor does it repel water like Nano Flex, but it is the softest, stretchiest winter tight fabric. The comfort is immediate and lasting. For the lower leg from just below the knee, we switch to our Nano Flex fleeced stretch-woven fabric that's both warm and highly water repellent for protection against spray coming off wet roads. It's also highly stretchy, and we leave a raw edge so we can construct the ankles without zippers while making sure the tight remains easy to put on and take off.

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

Made to Race 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.

Not Based on Pro Feedback Getting feedback from Team Ineos this year has meant trips to Belgium, Nice, Manchester and all around Italy, as well as Skype calls based around racing and training schedules. The recurring feedback from the riders is that their Free Bibshort (the same one you could buy in 2018) is really, really good. The only requested changes were a loop in the bib to hold the microphone for the race radio and one rider who wanted his seat pad moved back a bit. And it's not only Team Ineos that likes it. The 2018 Free Aero Race Bibshort is the best-selling Castelli short of all time. So for 2019 we've made some dramatic changes.

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

Innovative evolution The free aero RC bibshort is our top race short, which also means that it's insanely comfortable even if you never pin on a number. It's fair to say that we've been working on this short for the past 15 years. That's how long it's been since the original free aero race bibshort was first introduced, initially as our top-of-the-line race short. The various versions of the free have dressed all our pro women's teams over this time, and it also became the best-selling women's short in the history of Castelli because simply put, this is the short that does everything well. The concept is quite simple: start with the best pad we know how to make, surround it with a supportive short with good muscle compression, and then remove everything else that's not absolutely necessary. You feel free thanks to the reduced number of panels and the reduced number of seams. In fact, the short portion has just 5 panels compared to 10 in the previous generation. You feel free because of further refinements to the Progetto x2 air seamless seat pad. The two densities of foam plus the gel pads provide progressive damping, while the separate skincare layer is soft and stretchy to move with your skin. You feel free thanks to the most minimal bibs you've ever seen in a short, including open-weave straps for maximum airflow. But we reinforced the yoke so the straps stay in place and made the mesh back narrow for coverage that is minimal yet just enough to hold the shorts in place. And the bib elegantly frames a convenient pocket at the center back. You feel free because this is the first high-end short that doesn't need any sort of gripper or elastic at the end of the leg to keep the leg in place. Getting this right meant 28 prototypes and our most extensive test program ever, and it results in the most comfortable leg ending we've ever made. The Forza 2 fabric has 32% lycra with a high modulus for exceptional muscle support and just the right amount of compression. There's reflective piping on the back. And all logos are either stitched or embossed for durability. - High-compression 215 g Forza 2 fabric with 32% Lycra® content provides exceptional muscle support and compression - Women’s-specific Progetto X2 Air Donna seamless seat pad is soft against the skin but well padded for long-distance comfort - 5-panel construction for reduced seams and less chafing - Stitched scorpion logo patch and embossed Castelli wordmark for durability - Reflective piping on back of legs - Raw-cut edge at waist for extra stretch and comfort - Raw-cut leg ending engineered to stay put without silicone grippers

The perfect mix of comfort and speed. Engineered for top-level racing, which also makes it supremely comfortable for every ride and rider. - High-compression 215 g Forza 2 fabric with 32% Lycra® content provides exceptional muscle support and compression - Women's-specific Progetto X2 Air Donna seamless seat pad is soft against the skin but well padded for long-distance comfort - Minimalist bib straps allow maximum airflow, while a reinforced yoke keeps the straps flat over the shoulders - Rear mesh pocket - 5-panel construction for reduced seams and less chafing - Stitched scorpion logo patch and embossed Castelli wordmark for durability

The best all-around distance race suit without sleeves The idea behind this suit is fairly simple: castelli's best all-around long-distance race suit but in a sleeveless version. This suit trades the on-bike aerodynamic advantages of sleeves for the comfort and cooling of a sleeveless top. Everything else is full race performance. The short portion is built around comfort, with compressive fabrics for muscle support, the giro4 leg gripper that holds the leg securely in place without binding, and the kiss tri seat pad that provides good padding and comfort on the bike yet is hardly noticeable on the run. The upper portion features the castelli sanremo overlapping front opening to optimize fit during the swim and run when you're fully stretched out, while avoiding folds when hunched over in the bike position. Not to mention the convenience for nature breaks. There are two generous rear pockets, and the armholes have been constructed to reduce chafing during the run. If you're not fighting for the win or a kona slot, maybe the comfort-aerodynamics trade-off is worth it. - Second-generation sanremo sleeveless suit is faster than ever - Velocity rev2 main body fabric delivers aerodynamics with excellent fit and moisture management - Back fabric is our velocity mesh for breathability, yet it blocks 94% of uv rays for significant sun protection (upf 16) - Construction around armhole to reduce chafing - Castelli's sanremo front opening makes it easier to bend for cycling and straighten out for the run and swim, while also allowing for easier nature breaks or opening up for extra-hot runs

This suit trades the on-bike aerodynamic advantages of sleeves for the comfort and cooling of a sleeveless top. Everything else is full race performance. The short portion is built around comfort, with compressive fabrics for muscle support, the giro4 leg gripper that holds the leg securely in place without the dreaded sausage effect, and the kiss tri seat pad that provides good padding and comfort on the bike yet is hardly noticeable on the run.

Light, Cool and Straight Out of the Future We've been pushing the envelope on lightweight shorts since 2011 but have butted up against the limits of compromising durability for ever lighter weight. We needed to step back and find a better way. We examined what the short really needs to do: it needs to hold the seat pad securely in place while otherwise adding as little weight or fabric as absolutely necessary (without being transparent, obviously), and it needs to last a season of hard use. So we engineered a brand-new fabric using a woven, rather than knit, construction that shaves 30% in weight for the same level of support and non-transparency. Then we worked with the world's leading mill to construct a gradient fabric that becomes increasingly lighter the farther down the leg it extends, with the last part weighing a mere 90 g/m2 compared to normal short fabric, which weighs around 220 g/m2. This fabric, while being insanely light, maintains a decent durability along with excellent abrasion resistance, at least against the saddle. We don't guarantee it against unplanned slides across the asphalt, so please keep the rubber side down! Note that while the short saves a mere 48 grams while dry, this means it also absorbs around 30% less moisture when you're sweating. So when you're sweating your way up the Alpe d'Huez you're actually saving closer to 150 grams. This short doesn't compromise on comfort. We use our top Progetto X2 Air Seamless seat pad, the spectacular striped mesh bibs from the Free Aero Race 4 Bibshort and a flat stretch woven leg gripper to keep everything in place. - The premium lightweight hot weather short - Gradient stretch woven fabric for minimal weight with optimum support - Ultralight fabric to reduce weight by up to 50% while improving durability - Minimalist stripe mesh bib to minimize weight and keep you cool - Integrated gripper elastic with exposed Lycra to hold leg in place - Embossed logos and stretch silicone scorpion heat transfers - Progetto X2 Air Seamless seat pad

Everything We Know About Comfort This short is the result of decades spent working to make long hours in the saddle ever more comfortable. The fabric is our high-stretch Forza fabric. The 38% Lycra content means that it's gently compressive while never binding. And it maintains an insanely soft hand. The nearly seamless construction is derived from our Body Paint shorts, which debuted a decade ago and started the trend of reduced seams while maintaining remarkable fit. Nothing to rub or break. The renowned Progetto X2 Air Seamless seat pad gets an update in this season with a new skin care layer that features a remarkably soft new surface fabric and more stretch, which allows us to eliminate the front triangle. We also obsessed over every other little detail, like the new bib construction and even new silicone logos that stretch with the base fabric and recall the logo location of the first Castelli Aero Short from the late ’70s, the short that started it all. Product Features - Forza fabric with 38% Lycra content for perfect fit - Dual-layer lumbar support band keeps shorts locked in place around waist - Reduced seaming for more comfort - Raw-edge leg ending with vertical silicone grippers - Mesh back with bonded 2-layer bib straps - Silicone Castelli logos - Progetto X2 Air Seamless seat pad - 15°-30°C / 59°-89°F - Weight: 211g
