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.

Minimalist, superlight liner shorts for low-intensity riding. Engineered with our new, less aggressive Sport Touring insert, a more secure fit, and an ultralight, utltrabreathable textile.
The new Sport Touring TRAIL TACTICA Liner Shorts are engineered for less-intense applications — touring, the bike park, ebikes, and commuting. They’re refined for pure utility with minimal weight and ultimate breathability, so they layer seamlessly under any shorts or pants. The waist construction and leg bands are the same as the more robust TACTICA HP liner, wrapping the waist and thighs with lightly compressive security. The minimalist OFF-ROAD ST T3 Insert is 33% thinner than the High Performance model in our TACTICA HP T3 liner, though its dual layer construction erases microvibrations and diffuses shocks and larger impacts.

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.
The absence of bib straps compounds the difficulty of dialing the perfect ride-tuned fit. To address that, we reimagined the waistband with a stabilizing elastic layer that anchors the fit and an additional top band of mesh that extends coverage, independent of the elastic band, for comfort, moisture management, and to eliminate gaps between shorts and jersey while in the saddle. The updated insert features increased ventilation, a reduced footprint, and a new Odor Control Top Sheet Tex in Sugar Blue.

Short rides, big rides, indoor training, and everything in between—the MILLE GT Half Shorts are willing and able. To live up to their reputation of providing long-distance comfort, they’ve been treated with our proven Type.429 Titanio material, which is a lightly compressive textile with high elasticity, ensuring a comfortable and consistent hold on your legs while pedaling. The insert is the plush MILLE EVO, equipped with 8mm of memory foam, a black 3D waffle topsheet, and now updated with the kraterCooler system to boost breathability.
The make or break point of any bib-less short comes down to the waistband design, and the MILLE delivers. The breathable, supersoft Aerofit material at the front, using a fold-over construction that comfortably holds the shorts in place across the abdominals. At the rear section, our tall elastic hem mirrors the superFlat grippers at the lower legs, adding a secure, stay-put fit.

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.
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. Streamlined performance for all-day cycling with our standard leg length.

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.

Summer-weight knickers that offer extended coverage for UV protection and moisture management, wrapping the legs down to the upper calves in compressive breathability.
Assos' new hipClick construction gives the UMA GT Summer Knickers the steady, stabilizing fit of bib knickers but without the layering hassle and discomfort of bib straps. They’re built for long rides in warm conditions, with coverage that extends UV protection, light compression, and moisture management below the knees. The pre-shaped panels and high-stretch qualities conform to the legs without inhibiting the pedal stroke, and the updated UMA GT C2 insert increases endurance comfort with cushioning for a more upright, less aggressive riding position.

We like a comfortable bib short that's compressive, but not restricting. When we're riding up a canyon with burning thighs and the will to power through, the last thing we want is discomfort from our bibs or jersey. Assos designs gear for these moments so athletes can carry on pedaling through the tough stuff without a hitch. The brand's T GTS - Mille GT C2 Bib Short ensures that riders will have a good time on their bike no matter if it's a training session or a Sunday morning ride with the group. Custom fabric blends, a refined insert, and versatile fit ensure lasting comfort on all rides. For a performance-based balance, the Mille elastic interface insert is employed with 13mm of memory foam to ensure cushioning, and a 3D waffle perforated foam increases breathability in turn. Lightly compressive 4-way stretch ensures flexibility in the bib's fabric, and superFlat grippers keep everything in place without excessive pressure. Reflective accents offer additional safety measures in low-light situations.

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.

Trusted by committed riders the world over, the time-tested MILLE GT Bib Short is defined by its frictionless waist, air-cooling insert, and muscle-wrapping textile.
Assos leaned more toward comfort versus race in the bib shorts’ design, which mates a custom fabric blend with their regularFit to result in a performance piece for training, racing, or simply riding in total comfort. Assos built the bib shorts with a lightly compressive textile with high elasticity to ensure a comfortable and consistent hold on your legs while pedaling. At the front waist Assos used a raw cut with taped reinforcement to ensure the cleanest and most comfortable transition possible between the abdominals and front fabric panel. To construct the back panel, Assos recruited their acclaimed design to produce a flat, stable structure that disappears between the shoulder blades for a smooth supportive hold.

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.

Breathable, lightly insulated tights engineered for cool spring and fall conditions, updated with increased fit security and a more comfortable long-distance insert.
We completely reengineered our Spring Fall Half Tights with a new waist design and a new insert – in short, it’s an entirely new platform. The new waist is our hipClick construction, which stabilizes the leg panels and insert by locking into place with a supportive, unrestrictive fit. The updated UMA GT C2 insert shifts cushioning to support more upright, less aggressive riding positions – ideal for comfort over longer distances while training or touring.

The definitive bib shorts for competitive, committed cyclists from the company that originally defined the racing shorts genre—and continues to lead in driving it forward.
It’s only fitting that the latest generation of ASSOS inserts—the most advanced available from any manufacturer—is partnered with bib shorts completely re-engineered, with no design choice taken for granted or left unquestioned. The resulting bib shorts are atypically advanced—which makes them typically ASSOS. The shorts combine textiles and technology in an interwoven network of wrapping compression, silky comfort, and tensile pre-load to keep everything from the leg panels to the insert securely in place. It’s taken six years of in-house development and testing by WorldTour riders, but the EQUIPE RS S9 Bib Shorts are the definitive statement in cycling shorts from the cycling shorts company.

The next evolution in total comfort for winter bib tights, refined with increased insulation and a deeper, plusher insert.
The new RX EVO Plus textile is the most insulating of the RX Evo family. The added insulating qualities of RX EVO Plus textile handle colder conditions than the previous model, reducing the gap to the ULTRAZ counterpart without risking overheating in all but winter's worst weather. The new material breathes well to maintain a dry, warm microclimate, and 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.

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.

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
$200.00
Bringing up the rear of the exclusive River City Bicycles Acrostic kit, the Free Aero Race 4 Bibshort is Castelli's top race short, which also means that it's insanely comfortable even if you never pin on a number. The original Free Aero Race Bibshort was first introduced over a decade ago and has logged literally millions of kilometers under the backsides of their sponsored pro riders and has been the best-selling short both in the Castelli retail collection and in their Servizio Corse custom program. Over this time the short has undergone numerous updates and improvements in the never-ending quest to create the best short. While the basic concept of a minimalist workhorse pro-level comfortable race short remains, every single fabric, component, stitch and construction method has been updated and improved over time. The fourth major generation of the short features the updated Progetto X2 Air Seamless seat pad. This pad separates a soft, stretchy skin care layer that moves with your body from a generously padded cushioning layer that replicates the form of your saddle. Eight-hour rides are no problem. Of course the fabrics are premium, made to Castelli's specifications by Italy's best fabric suppliers. The Forza fabric on the inner leg features 38% Lycra® content for perfect fit, while the Vortex fabric on the side panels is dimpled for aerodynamics. And it's held in place by the latest iteration of Castelli's seamless flat Giro leg gripper.
$200.00
