Shorts/Bottoms

It doesn't matter if you're heading out for an after work hot lap or gearing up for an all-day epic; the Women's Summit Short is the right choice for every trail. These premium shorts feature an ultra-comfortable liner with our new Women's Levitate chamois, and a tailored fit that works with your favorite knee guards. Perforated panels on the inside of the legs keep the Summit feeling airy, while dual Trail Access pockets keep the day's essentials close at hand, yet out of the way, so they don't interfere with pedaling. Chances are this short will become your go-to.

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

Competitive bib shorts that combine our most advanced S9 platform—developed with years of research and WorldTour feedback—with a female-specific design. Durable enough for daily use; engineered specifically for racing. Why we made it We spent a total of six years developing prototypes and gathering feedback from cycling's biggest stage, leaving no design choice unexamined and no convention unchallenged.

Thermal bib shorts for training and racing in the cool, dry conditions of spring and fall. These shorts are built for cyclists committed to the racing and training program, regardless of falling temperatures. BEHIND THE PRODUCT These bib shorts are appropriate for cooler temperatures that don’t yet warrant knee or full-leg coverage. The thermal insulation is reinforced with inclusions (the twinDeck construction on the crotch panel) and omissions (we left out the kraterCooler chamois ventilation in that same panel) designed to preserve core warmth without providing too much coverage. The balance of warmth and breathability recommend these shorts for tempo efforts and base miles in cool temperatures, and the addition of warmers—secured with the shorts’ Ultralight Leg Grippers—lets them follow the mercury still further down the thermometer.

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. Type.429 is flexible enough for a streamlined fit; breathable enough for the heights of summer; compressive enough to respond to and support your body; and substantial enough to resist the abuse of countless kilometers. A true daily workhorse. C2 AEPD regularFit is based on our performance race models but tuned for comfort with a more forgiving Zero-Pressure waist.

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 Donna seat pad. 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 - ISS Air2 Donna seat pad for all-day comfort

Our go-to men's bib tight is made for those days when comfort depends on consistent warmth. To deliver a great shoulder season riding experience, Thermal fleece fabric insulates and transfers moisture efficiently, while PI Dry water-shedding technology wards off splashes and light rain. Fewer panels and reduced seaming, combined with a stretchier fabric, has improved both fit and comfort. And, the material is so stretchy, we've been able to eliminate the zipper from the ankles, improving both durability and comfort. Raw-edge bib straps eliminate bulk for improved layering comfort. These tights do not have a chamois, allowing you to pull them over your favorite shorts or use them for other cold-weather activities. - Ultra-soft Thermal fleece fabric for pedaling comfort and thermal regulation - Made with recycled material - PI Dry technology for permanent water-shedding performance - Eliminated zippers at the ankles for improved fit and comfort - BioViz reflective elements for low-light visibility - Lower Panel: 56% nylon, 30% polyester, 14% Lycra elastane Upper Panel: 75% nylon, 25% elastane - Made in Vietnam - Type: Thermal - Reflectivity: Low-light visibility

Optimal freedom of movement and comfort in the saddle come thanks to a seam-free gusset and reinforced 4-way stretch Ripstop fabric. Any rider can easily find a secure fit thanks to Velcro adjusters on the waistline. It's easy to carry belongings and keep them secure in the envelope closure pockets on the thighs and the zipped rear card pocket. Zipped openings on the thighs give great ventilation and the shorts are cut to fit perfectly with knee pads.

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

This is our warmest tight, for tough guys who don’t let a little cold keep them indoors. 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 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

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.

Mountain bikers need clothing solutions too, so we set about extending our premium, mountain bike-specific OFFROAD collection. Our apparel engineering team were tasked with the challenge of creating a breathable yet durable short that has signature ASSOS performance yet doesn’t break the bank. The result of their hard work is these XC-specific bib shorts, for which we just can’t find enough superlatives. Employing the ripstop, high abrasion resistant and breathable dyneRope fabric (which is stronger than steel), these shorts have been put through their paces by the BMC MTB Racing Team’s best riders. And with such stringent world class testers giving their approval, it’s clear that the pedigree of these shorts has already been confirmed. The result is a tough, lightweight and highly breathable pair of shorts that are perfect for the toughest XC trails. According to the team, the dyneRope on the outside of the legs wicks sweat like no other, delivering a seriously world-class performance that saw the riders sweep the team standings at the 2017 UCI MTB World Cup series. But no matter how hard you’re pushing while riding off-road, there’s always a need for superior ASSOS comfort in the saddle so we’ve opted for our opulent MTB-specific insert. Placed a little further forward than its road counterpart, it is tuned for the steepest climbs and sickest flow trails with memory foam. From the UCI Mountain Bike World Cup to your home trails, it’s time to hit the dirt.

A breathable, lightly insulated half knicker engineered for spring/fall conditions when tights are too warm and shorts are too cool. We engineered these knickers for fall and spring rides where knee coverage and a touch of insulation are just the ticket, as they feature a blend of ultrasoft and insulating fabrics, along with our proven female-specific insert and signature regularFit. RX EVO makes up the majority of the paneling. This brushed warp-knit fabric provides exceptional comfort, wicks moisture, adds high levels of insulation, and remains extremely flexible. The waist benefits from ultrasoft warp-knit Aerofit, which is knitted with an open structure for maximum ventilation and featuring high elasticity plus built-in odorControl. The knickers' fabric technology ensures that the fronts of your legs stay shielded from biting winds and cold air, while the backs benefit from added breathability. Its fold-over front panel design at the waist creates a smooth, pressure-free transition between the body and fabric.
