Meticulous detail was put into the cut of these UMA GT bib-less cycling shorts, applying their super stretch aeroFit fabric on the abdomen to ensure a flawless fit whether you’re racking up summer miles or conducting indoor training sessions in winter.

Assos' H.MilleShorts are perfect for warm-weather riding, as a base chamois under winter tights, or simply for those who prefer the upper-body freedom of movement that comes with suspender-free shorts. They're light, comfortable, minimize waist constriction, and employ Assos' conforming chamois for full support.
Adaptable, all-mountain riding shorts with a streamlined design, ultralight textiles, and comfort-boosting features. This short is a shell, does not have padding.
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. The precise fit comes down to the waistband design, where Assos applied their breathable, ultrasoft Aerofit material at the front, using a fold-over construction that comfortably holds the shorts in place across the abdominals. They did the same at the lower legs, adding a secure, stay-put fit with an asymmetrical hold on the thighs. Compared to the Assos Laalalai shorts, these are 2.5cm shorter in length. And in terms of the insert, they feature the lightweight, breathable S7 EVO to deliver targeted support and all-day comfort.
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 Assos' 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.
Matchless performance and flawless comfort. The H.laalalaiShorts_s7 feature the best materials and the smartest female-specific design to ensure these padded cycling shorts rise to the occasion on the toughest rides. A faultless fit is more than an aspiration, it’s a basic requirement with ASSOS cycling clothing. The importance of this is highlighted in the bib-less short, with no straps to hold everything in place. Rest easy: with these carefully designed women’s cycling shorts the rider is guaranteed total comfort. Beyond the appealing clean aesthetic of the H.laalalaiShorts_s7 there are many less eye-catching features that we know are crucial. An all-new waist construction ensures the fit remains spot on however hard the ride. The Lady_S7 insert has been precisely crafted to fit the body of the female rider and moves in sync with her body throughout the ride. Even the half-leg flat grippers are a cut above, a barely-there flourish. The regularFit of the H.laalalaiShorts_s7 offers a subtle, universal cut that makes these padded cycling shorts work perfectly for all types of riding.
Train, race, and simply ride in total comfort with the MILLE GT Bib Shorts’ custom fabric blend and celebrated insert design. They’ve been treated with Assos' proven Type.429 Titanio material, which is a durable, lightly compressive textile with high elasticity, ensuring a comfortable and consistent hold on your legs while pedaling. This workhorse textile, mated with a regularFit that leans more in the direction of comfort versus race, is what defines MILLE as the go-to ASSOS shorts so many cyclists reach for day in and day out. Combine that with the plush MILLE EVO insert, equipped with 8mm of memory foam, a black 3D waffle topsheet, and now updated with their kraterCooler system to boost breathability—and you have the complete recipe for full-day comfort in the saddle. The back panel is constructed using Assos' acclaimed Y7 Frame Carrier design and Stabilizator mesh, resulting in a flat, stable structure that disappears between the shoulder blades for a smooth, supportive hold.
Engineered for cool conditions, the MILLE GT Spring/Fall Knickers employ light insulation and extended knee coverage for long-distance comfort and protection.
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.
The T.Laalalaishorts_S7 are the first female-specific S7 bib shorts from Assos. After changing the game for the men, they have now developed a women’s version of these ground-breaking shorts, allowing everyone to experience Royal Comfort while on the bike. Taking everything they have learned from their S7 generation of shorts, they have created something revolutionary for the female rider who demands superior performance. With their all-new insert, a cut that improves comfort, new clasp, and enhanced bibs and back, these bib shorts are a game changer for female cyclists. These are the ASSOS women’s bib shorts that set the new standard. Taking all the technologies from their S7 generation of shorts, these are the perfect shorts for the female rider who demands the most from her apparel. THE KEY FEATURES - Female-specific S7 generation insert - Wider bibs for added comfort - Refined mono-bib - External elastic on the legs for added comfort - Made with type.439 material for increased performance - type.221 mesh material on the back for added breathability - Magnetic clasp on the mono-bib for easier closing and added comfort

Cento is synonymous with long-distance comfort, and the latest iteration of this fully loaded bib short takes that sentiment a step further. Enter the T Cento EVO: Assos' favorite comfort fit platform, evolved with an updated insert and refinements throughout. Assos began with the same Type 439 textile for the main panels, as it's incredibly comfortable against the skin. With two different rates of four-way stretch, it also delivers a nice, compressive hold for a smooth, supportive wrap along the thighs. This proprietary fabric provides exceptional breathability, and it rapidly transfers moisture to its quick-drying outer surface. As with the original Cento, the fit is a touch more generous around the lower abdominals than Assos' racingFit options, and they added their new raw-cut zeroWaist to ensure a smooth and comfortable hold on a variety of body types.
With six years of technology developments and Assos’ most advanced race insert to date, the Equipe RS Bib Shorts S9 forges new ground, bringing unmatched stability and comfort to your most demanding speed-focused applications. These bibs employ A-Lock Engineering, Assos' new bracing system, comprising proprietary textiles and technologies working together to stabilize the shorts and secure the insert in place. The S9 generation incorporates just two panels, with a primary “butterfly” panel fully wrapping the legs and converging in the rear to form the ergoBox structure. This design effectively frames the insert in place and provides you with an ultra-comfortable wrap on your legs using our Type 441 textile, developed specifically for compressive hold and silky comfort. From here they added their unique rollBar, which mimics a race car’s anti-sway bar by using the bib straps to stabilize the insert as your weight transfers from left to right while cornering. Each strap is sewn into the seam directly above the insert, ensuring it’s under pre-loaded tension at all times. The bib straps have also been redesigned using calibrated stretch throughout, with the rear section using a single section of elastic material—folded over on itself—forming an A-frame in the back. It delivers limited vertical stretch in order to add further stability. In the front, the straps are made of a more flexible material, with an antibacterial carbon weave, to wick moisture and lay flat. Assos also focused on a single insert platform, which allowed the freedom to reassess what is most crucial to a streamlined, race-spec insert. They reduced the overall footprint to shed additional weight, employed superAir microShock foam with 3D waffle, incorporated the kraterCooler system to increase airflow up front, and took additional measures to anchor the insert at the rear with a patented horizontal stabilizer. The result? Signature Assos comfort, stabilized.
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.

Soft Thermoflex fabric with the Kiss pad
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
