Shorts and Knickers

$79.99 $139.00 42% Off
The Trail Cargo Shorts take the concept of adaptable, all-mountain shorts to a new realm, made possible by streamlined tailoring and progressive materials. They've been developed with a waistband that smoothly holds the shorts in place, a cut that's trim around the crotch to avoid saddle snag, a length that's ideal with or without pads, and a versatile new fabric that flexes with each pedal stroke.

The UMA GT Women’s Half Shorts set a new standard in on-the-bike comfort and female-specific design. The UMA GT Women’s Half Shorts blend several proven textiles and construction techniques to create a truly unique pair of shorts that are as fast as they are comfortable. Like our high-end Laalalai Shorts, they’re cut from Type.439 Diadema, a fabric chosen for its exceptional stretch, high-wicking, and compressive capabilities. Wind-tunnel tested and using our aerodynamic Fenomeno1 design, these are our some of our fastest women’s cycling shorts yet. The precise fit comes down to the waistband design, where we applied our breathable, ultrasoft Aerofit material at the front, using a fold-over construction that comfortably holds the shorts in place across the abdominals. We did the same at the lower legs, adding a secure, stay-put fit with an asymmetrical hold on the thighs. Compared to our Laalalai shorts, these are 2.5cm shorter in length. And in terms of the insert, we’ve sewn in the lightweight, breathable S7 EVO to deliver targeted support and all-day comfort.
$155.00
A bib-free training and endurance cycling short that's at home on the road or aboard the indoor trainer. Bibs aren't for everyone, but their absence compounds the difficulty of dialing the perfect ride-tuned fit. The bib-free Zero-Pressure waist embodies our C2 AEPD click-fit ethos with a secure hold on the sides and back, and a panel insert on the front stretches to accommodate aggressive positioning on the bike and deep breathing during hard efforts. The updated insert inherited increased ventilation from our premium models, and 3mm of additional thickness increase long-ride comfort. - 80%PA 20%EA
$155.00
Bib-free shorts engineered for utility and all-day comfort. Built for base miles and endurance epics, whether they’re on the road or the indoor trainer.
$170.00
A new bib short platform for committed daily riding, whether that’s dedicated training regimens, the weekly crit series, or weekend centuries.
$180.00
The next generation in committed riders' bib shorts of choice, defined by its frictionless waist, refined air-cooling insert, and muscle-wrapping textile. We took this generational redesign as an opportunity to make the MILLE GT better at the things we loved about its predecessor, including our premium X-frame suspension carriage, a refined comfort waist fit, and a reduction in seams and weight (28% and 5g, respectively). The insert also got some attention, inheriting the increased ventilation of our GTS/GTO models and receiving 3mm of additional cushioning. We also updated the Odor Control Top Sheet Tex to the Sugar Blue colorway. - 80%PA 20%EA

The entry into our Race Series, EQUIPE R combines technology from the EQUIPE RS system with simplified, everyday utility. The EQUIPE R is built with our signature A-Lock Engineering construction that adapts technologies from the WorldTour-proven EQUIPE RS. It maintains racing it stability with a muscle-wrapping butterfly panel and the new Type.443 textile, which compresses and breathes like the EQUIPE RS, but with a deeper black color. Monofilament elastic in the bib straps reduces weight and dries faster than dual-layer models, and the shorts are equipped with our core racing insert. - 80%PA 20%EA
$220.00
GTS marks the introduction of the second generation of MILLE—an all-new bib short that builds on the iconic GT shorts’ Total Comfort formula with its plush double-layer insert and a fatigue-reducing textile. Assos engineered it for committed riders looking for added comfort during training to everyday riders seeking maximum long-distance support.
$230.00
Lightly insulated knickers for cool conditions and long-distance riding, with extended knee coverage and stormproof textiles. Updated with features to enhance stability, reduce seams, and improve support. We redesigned the pre-shaped panels to reduce seam count, and we also shed grams without sacrificing the light compression and long-distance comfort MILLE embodies. The Knickers are updated with our race-inspired X-Frame bib design, which stabilizes the insert and body panels throughout the pedal motion and while cornering. The new model is also updated with our MILLE GT C2 insert, which adds 2mm of plush comfort for long rides maintaining form or building base miles for the coming season. - 86%PA 14%EA

From the compressive, all-day comfort of the fit to the high-wear fabrics and additional cargo space, these bib shorts check all the boxes for gravel and touring support. Gravel, touring, and bikepacking require more robust equipment. Frame, wheels, tires, clothing—none of a rider’s gear is exempt, so the KIESPANZER (or “Gravel Tank”) provides the requisite durability for the inevitable abuse of cycling beyond the tarmac. It’s also equipped with storage solutions for day-trip supplies or to supplement pack space and keep ride essentials readily accessible in pockets of high-stretch, extremely breathable 3-Mesh panels. Reflective stripes help ensure visibility on early departures, late returns, or those long dusks while pushing through the final miles to the next hotel or campsite.

The lightest, most breathable ASSOS bib shorts to date. Engineered specifically for full-gas efforts in the hottest conditions—indoors and out—the 120-gram SUPERLÉGER is built on our S9 platform using hyperlight textiles for unmatched stability and boosted ventilation. BEHIND THE PRODUCT To not only reduce weight, but also increase rider comfort and support during the hottest racing days and flat-out indoor training sessions. We reduced the number of seams and replaced current panels’ textiles with hyperlight, more breathable materials to further reduce friction and keep the leg muscles cooler and fresher, for longer durations.
$350.00
GTO marks the pinnacle of the Total Comfort MILLE GT line - spiritual successor to the iconic CENTO and Campionissimo Bib Shorts. It features the plushest, most responsive and breathable ASSOS insert to date, wrapped in our new frictionless, wrinkle-free paneling. The GTO has two leg lengths: STANDARD and LONG (+3cm vs standard). BEHIND THE PRODUCT With large-muscle support, friction, and excessive pressure remaining critical issues on long-duration rides, GTO destroys conventional bib short construction formulas. We reversed stitch lines and radically reshaped the insert to eliminate friction and genital pressure, while providing matchless muscle support with tapered, wrinkle-free leg panels that mirror your personal physique.

Soft Thermoflex fabric with the Kiss pad
$100.00
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.
$100.00
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

Don't Limit Yourself We made this short to meet Castelli's high standards for comfort and performance in a cycling short while adding a few extra features that come in handy for riding on any surface. You'll find our normal exceptional fit as well as the KISS Air2 seat pad, which provides generous anatomically placed padding with an exceptionally soft top layer. What makes this short special is the extremely durable Unlimited Lycra fabric. It has higher abrasion resistance and tear resistance while not compromising on stretch, moisture management or comfort. In addition, we use double-layer side panels for the old track rider's trick of fabric-sliding-on-fabric should you fall. This short isn't really meant to be indestructible, but it significantly increases the chances that sliding out on gravel will mean you need to just brush yourself off rather than having to buy a new pair of shorts. That second layer on the side panel also makes for convenient side pockets, with a flap over the top to prevent the contents from falling out. For added convenience while riding on and off road, you have two mesh pockets on the lower back that compress gear next to your body to keep it from bouncing around. This short adds durability and storage without compromising comfort — for unlimited amounts of fun. - Made for fast riding on unlimited terrain - 200 g/m2 nylon/Lycra fabric with best-in-class abrasion and tear resistance - 2 mesh rear pockets built into mesh bib straps - Double-layer side panels reduce abrasion if you fall, while also creating 2 useful side pockets - Raw-cut leg ending with vertical silicone grip strips to hold leg in place - KISS Air2 seat pad for long-distance comfort - 15°-32°C / 59°-90°F - Weight: 200g

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 donna seamless seat pad in a mostly 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. On your long endurance rides you'll especially appreciate castelli's drop-tail bib construction. The wider bib straps are free floating so you can cross them in front or back. They pull tight enough to keep your shorts in place, but when the need arises they stretch long enough that you can take a bathroom break without having to remove your jersey and bibs. 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 - Bib straps can cross in front or back and are extra elastic, allowing short to be pulled down for pee stops without removing bibs - Women's-specific progetto x2 air donna seamless seat pad for even greater comfort and improved airflow - Giro3 leg grippers lie flat

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 Giri 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

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
