The main story of this short is the use of our renowned top-of-the-line Progetto X2 Air Seamless seat pad in an otherwise traditional short, but in fact every little detail has been obsessed over to ensure your comfort on your next long endurance ride. A great pad is useless without great fit. The seams are placed around the hip area to create a perfect shape on the bike. The Endurance Evolution fabric has a soft hand while providing good compression and excellent moisture management. And it's all held in place with the amazingly comfortable GIRO3 leg gripper. This short offers exceptional value and is ready to deliver lasting comfort on your longest rides. Endurance-level comfort for every ride with Castelli's most comfortable seat pad. - Endurance Evolution fabric provides optimum muscle support and feels drier in nearly all conditions - Anatomic cut for perfect on-bike fit - Progetto X2 Air Seamless seat pad for even greater comfort and improved airflow - GIRO3 leg grippers lie flat - Weight: 186g

The Entrata Bibtight reflects the same obsessive drive for function, comfort and performance seen in all our tights, combined with fabrics and components that were top of the line a few years ago. Our Thermoflex fabric was considered a breakthrough, the best you could get, until a decade ago when we developed Nano Flex and added water repellency. If you don't ride in cold, wet conditions you'll appreciate the luxurious warmth and stretch of this fabric. The tight has minimal seams for comfort, and our KISS Air2 seat pad features generous padding and quite possibly the softest surface fabric in the business. It's everything you need to comfortably enjoy dry winter rides. - Thermoflex fabric for warmth and comfort - KISS Air2 seat pad is so good it's the choice of some of our pro riders - Mesh bib straps - Ankle zippers for easy on/off - Reflective logo below knee - Reflective flap over ankle zipper for extra visibility

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

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. Since then it has won three Tours de France, three Gri d'Italia, one Vuelta, and San Remo, but it also became the best-selling product 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 215g Forza 2 fabric with 32% lycra content provides exceptional muscle support and compression - Progetto X2 air 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 - Sublimation-printed graphic and logos that will never peel, crack, or fade - Reflective piping on back of legs - Soft waistband with raw-cut edge panels for extra stretch and comfort - Raw-cut leg ending engineered to stay put without silicone grippers

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, while the Instadry speed fabric provides the support you need, and here you'll appreciate the extra support layer in the front. - 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

The Premio Bibshort has been engineered to provide the ultimate in long-distance comfort and to be your favorite bibshort ever. That's a big claim, but there's a lot of development in this short to back it up. So let's take a tour of the short. The first thing you might notice is what's missing: the seams and multiple panels. We engineered a new fabric that changes depending on the needs over various parts of the body. The lower leg has a raw-cut leg ending and rubberized yarns to guarantee a flat grip to keep the leg in place. The fabric becomes lighter in the thigh, while the four-way stretch provides just the right amount of muscle support. In the pelvis area, the compression and support increase to keep the seat pad and everything else in place, and the fabric gets thicker to avoid any embarrassing transparency issues. With this magical fabric we don't need to stitch separate panels together, which ensures more comfort and a better fit, as well as a sleek, sophisticated look. The premium fabrics extend into the bib straps. The perforated back keeps you cool and the edge is bonded so you don't feel the thickness of a stitched edge. The elastic straps have just enough modulus (return) to hold your shorts securely in place without cutting in to your shoulders. The seat pad is our top-of-the-line Progetto X2 Air Seamless pad. It's actually two separate components: a soft, stretchy Skin Care Layer next to your skin, which has the sole purpose of preventing any rubbing on your skin, and, under that, the Cushioning Layer, which features two separate densities of foam along with breathable perforated gel inserts under the ischia bones and perineum. We've carried the less-is-more theme into the design, with minimalist laser-etched logos and subtle finishing. It looks as premium as it feels. You can tell that every component, every stitch, every detail has been obsessed over. You'll not find a better bibshort. - The premium all-conditions short - Gradient stretch woven fabric for the right support in the right place - Woven fabric weighs 30% less than comparable knit fabric - Perforated back bib panel with lie flat bib straps that don't bind at shoulders - Integrated gripper elastic at leg ending holds short in place without need for extra silicone grippers - Laser-etched logos with RossoCorsa at center back and black scorpion shadow logos at lower legs - Progetto X2 Air Seamless seat pad

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

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
