Shorts and Knickers

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

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

Designed for both endurance and performance, the Men's PRO Bib Shorts are the epitome of cycling excellence. Merging the luxurious feel of Italian PRO Transfer fabric with the innovative PRO Levitate chamois, these bib shorts provide superior stretch and body contouring for your most critical rides. Featuring a minimalist seven-panel construction to reduce seams and enhance fit, they are completed with wide, laser-cut bib straps and raw edge hems for a seamless transition to the skin, ensuring a secure and comfortable fit without the bulk. BioViz® reflective elements offer essential visibility for safety during low-light conditions. Whether pushing hard or enjoying a leisurely day on the road, these shorts promise to keep you comfortably in the saddle with undeniable style and functionality. - Luxurious Italian PRO Transfer fabric balances compression for ultimate comfort - Triple-density PRO Levitate chamois minimizes skin abrasion and sit bone discomfort while offering premium stretch for elevated contouring to the body - Seven-panel design minimizes seams and optimizes body-contouring fit - Laser-cut raw edge leg hem construction for seamless transition to skin - BioViz® powerful reflective elements that reach 100 meters for night visibility - 10.5" inseam

Crafted with long ride comfort at the top of the list, we paired our all new Levitate PRO Chamois with luxurious Italian PRO Transfer fabric to create a bib short that you will choose for your most important rides. Just seven carefully engineered panels are used to minimize seaming for a perfect contour to your body. Wide, laser-cut bib straps provide a barely-there, yet supportive fit. And raw edge hems create a smooth transition from short to skin for a sleek, high-performance look and feel, with a printed silicone gripper to hold it securely in place even during hard efforts.

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 perfect apparel for the perfect ride, that's what our Prime Series apparel is all about. The best fabrics, constructions, and technologies go into these pieces, and the Men's Prime Bib Shorts are no exception. Starting with the uppers, the open suspender design keeps the bibs right where you want them, without constricting any upper body movements. The suspender fabric is also extremely soft and plush, eliminating any shoulder discomfort or irritation, yet we've still built in a HookUp magnetic bib connection making nature breaks much easier. The pre-molded, triple-density foam Body Geometry Contour 3D Chamois is contoured to perfectly match the curvature of your body, all while being soft and supportive in all the right places. With the Prime Bib Shorts, you're sure to embrace the "chamois time is training time" motto as they're so comfortable, you won't want to take them off. - Open suspender construction keeps the bibs in place without constricting the upper body. - Stretchy elastic suspenders are extremely plush and soft against the skin. - Silicone-infused fabric cuff provides a gentle, secure hold on the legs to ensure a shift-free fit. - Fabric Content: MAIN: Knit 46% Polyamide, 38% Polyester, 16% Elastane - UPPER: 90% Polyester, 10% Elastane

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

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.

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 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
