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.

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.

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

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.

Our 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. - 80%PA 20%EA

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.

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. - 76%PA 24%EA

The HASHOOGI S11 defines the winter bib tights genre, combining our second warmest RX EVO textile with an updated insert that increases breathability without sacrificing warmth – a fast-drying insert translates to less internal moisture and less internal chill. Raw-cut edges reduce volume for easy, frictionless layering, and trickledown rollBar technology from the Racing Series increases stability while changing positions during long base-mile rides. The new insert and streamlined, endurance-tuned fit maintain total comfort for upright riding positions, and large reflective stripes positioned behind the knees flash light throughout the pedal stroke, increasing rider visibility in grey winter conditions.
