Shorts/Bottoms

The Thrill of Competition We made this short to incorporate as much technology as possible from our top-of-the-line pro-level race shorts at a more accessible price. And although it's certainly capable of weekend racing, it's also a great comfort performance short even if you never pin on a number. 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. The intangible part that you'll appreciate most is our knack for building in perfect fit, thanks to the Castelli pattern engineering team. This is the short that brings the best of Castelli's know-how in building comfort performance shorts into an accessible product in your cycling wardrobe. - KISS Air2 seat pad for all-day comfort - Affinity Pro Lycra fabric on inside of leg for outstanding stretch and rebound - Vortex BLC textured fabric on legs for better aerodynamics - Giro4 leg gripper with raw edge for comfort and silicone stripes for grip - Flat-lock stitching - Reflective detailing on back - Mesh straps for comfort and breathability - 15°-35°C / 59°-95°F - Weight: 173g

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 Evolution fabric provides optimum muscle support and feels drier in nearly all conditions - Anatomic cut for perfect on-bike fit - Mesh bib straps and back to keep you cooler - Progetto X2 Air Seamless seat pad for even greater comfort and improved airflow - GIRO3 leg grippers lie flat

The Entrata Thermal Tight brings you all the performance of the Entrata Thermal Bibtight, just without the bib straps. You'll appreciate the luxurious warmth and stretch of the soft brushed fleece Thermoflex 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 - Ankle zippers for easy on/off - Reflective logo below knee - Reflective flap over ankle zipper for extra visibility

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 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

Castelli's entry-level short still needs to be an amazing short in order to carry the scorpion logo. Comfort from quality fabrics, our KISS Air2 Donna seat pad and anatomic construction are brought together with an overall focus on durability. - KISS Air2 Donna 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 - Mesh bib straps for comfort and breathability

The baggy-short look without the feel, thanks to the slimmer fit and stretch woven fabric. It's ready for long-distance endurance rides, but it's also a great-looking casual short off the bike. - Stretch woven fabric with DWR finish - Extremely light so you won't even feel it on - 2 front pockets and 1 zippered rear pocket - Stretch waistband with zippered front opening - Scorpion button logo There are those days when a baggy short just seems like the right look. But you always debate whether you're willing to compromise comfort for that look, and you end up wearing Lycra®. So we set out to make a better baggy. We reached for a stretch woven fabric that gives great stretch but in an unbelievably lightweight yet durable fabric. We gave it a DWR finish so mud and water roll-off. We gave the short two top-opening pockets like jeans so that whatever you put in there won't fall out. We made the cut fairly close to the body so you look good off the bike but the short doesn't balloon out when you're on the bike. It all just kinda disappears. The short doesn't have its own seat pad, so wear this over your favorite Castelli short. The Superleggera is a good choice for warmer weather, or the Unlimited if you want the extra pockets.

This is our midrange performance short, great for a long ride or a quick hour workout indoors or out. Our endurance evolution fabric is a high-modulus, very matte lycra fabric that feels extremely dry while providing just the right amount of compression. The waist construction eliminates stitching and elastic and lies completely flat. At the leg ending we use a raw-cut edge with vertical silicone strips to keep the leg in place without the pressure that creates the dreaded sausage effect. A great short needs a great seat pad, and the women's-specific kiss air2 donna pad will keep you comfortable without being too bulky. - Endurance evolution fabric for a matte finish with high-modulus stretch - Raw-edge leg ending eliminates sausage effect while silicone print holds leg in place - High-visibility reflective patches at back of leg - Soft dual-layer waistband - Women's-specific kiss air2 donna seat pad for long-distance comfort
