The coolest, lightest summer cycling sock in our ASSOSOIRES collection. For the hottest days in the saddle, comfort is exactly equal to minimalist construction and cooling ventilation, so we lopped off the coverage of an extended cuff and engineered a barely there, highly breathable textile whose honeycomb weave actively pulls moisture to the surface. The seamless, 160-needle construction creates a soft, lightweight sheath of frictionless comfort. Reinforced toe ensures "lightweight" doesn't also describe durability. The firm band circling the foot offers noticeable arch support and cooling.

A summer-weight sock with hi-vis detailing for late training rides and twilight criteriums. Summer cycling isn't a strictly daytime activity. Some days start well before the sun rises; others end after it's set. This sock combines our lightweight summer breathability and cooling with a photoluminescent strip for low-light visibility. A lightweight Lycra blend delivers light compression and generous moisture management. STL (or Spot The Light) incorporates photoluminescent threads to add light to your pedal stroke in low-light conditions. The seamless, 160-needle construction creates a soft, lightweight sheath of frictionless comfort.

A classic cycling sock, updated with functional technology for cooling and support and a slightly longer cuff for a clean, current aesthetic. A piece of cycling equipment is effective when it does its job so well that you forget about it. Like their predecessors, the latest GT Socks embody that ethos, pulling moisture, resisting odor, and providing a light wrap of support across the metatarsals, arch, and ankle. We've updated the design with new yarns, improved ventilation, and a cuff height of 16cm (6in). - 90% PA 10% EA

Lightly insulated cycling socks for the cool, low-light days of early spring and late fall. The transitional seasons are defined by cool weather—a symptom of shorter, often overcast days. These socks combine light insulation and a prominent photoluminescent stripe to help keep your feet warm and your legs visible to other road users, flashing light through your pedal stroke. The unique geometrical knit also actively pulls moisture from your skin, preventing the accumulation of a clammy chill. Anti-odor polyamide blend reinforced with Lycra for support and light insulation. STL (or Spot The Light) incorporates photoluminescent threads to add light to your pedal stroke in low-light conditions. 160-needle construction eliminates seams for a frictionless fit that wraps in gently compressive support, preventing slumping or restrictive pinching at the cuff.

Styled to match the hottest days, the Assos monogramSocks evo8 are classic in their length and modernist in their patterning. Made from a comfortable blend of Polypropylene, Elastane, and Polyamide, their construction guarantees breathability and improved airflow–crucial factors while cycling. Closely contouring the foot, they’re suited to intensive riding in summer conditions.

The ideal sock for demanding rides in warmer climates, where breathability and targeted support are most crucial. To create an ultralight sock that’s as comfortable as it is supportive, Assos took a hard look at the yarns themselves. Testing in warm-weather conditions eventually led to Hydrogen, a buttery-soft microfiber that’s blended with Lycra to deliver a light compressive hold along the foot, ankle, and lower leg using a seamless construction. From there they targeted the arch, wrapping it with a ribbed band of airy mesh for further support and boosted breathability, along with a contrasting band along the Achilles for a clean finish.

Cycling socks with midweight insulation for riding in cold, low-light conditions. In cold weather, staying dry is imperative to staying warm, so we engineered a unique yarn that provides midweight insulation while transferring moisture like a summer sock, ensuring the added warmth isn't lost to clammy chill. We also added a strip of highly visible STL textile on the Achilles and a ring of Winter 3/3 blue around the arch, increasing your visibility on the road and your socks' visibility in a drawer of black cycling equipment. Cotton-wrapped elastomer provides soft, breathable insulation. STL (Spot The Light) incorporates photoluminescent threads to add light to your pedal stroke in low-light conditions. 160-needle construction eliminates seams for a frictionless fit that wraps in gently compressive support, preventing slumping or restrictive pinching at the cuff.

The lightest socks in the Race Series, engineered with a zero-rise cuff and a lightweight 240-needle construction. The low-rise SUPERLÉGER is the lightest, most breathable sock in the ASSOS layering system.

Midweight cycling socks with an extra tall cuff for extended coverage in cool weather. Versatility is key in transitional seasons, and knickers were conceived to provide this, but they do have one gap in performance: the gap on the shin and calf. The 28cm (11in) cuff on our SONNENSTRUMPF Spring Fall Socks bridge that gap by extending midweight insulation up the calf. Size Guide: 0 35-38 I 39-42

An extremely warm winter sock, updated with triple the insulation in key areas. The key to maintaining warm feet while riding in winter is to combine insulation with the ability to stay dry from the inside and the outside. These socks combine the stretch and moisture-management of synthetics with the superior insulation properties of wool. Compared to its predecessor, the insulation has then been tripled across the toe and up the blue panel beyond the arch, providing extreme warmth for the coldest days. 76%PL 20%WO 4%EA

MILLE 2.0, back with a more comfortable raw-cut sleeve construction, lighter fabrics, and its classic regular fit—your new staple for everyday training to long-distance weekend rides. Why we made it Since its debut, the MILLE has been a kit staple for countless riders due to its classic fit, comfortable textiles, and unmistakable ASSOS style. We took note of what made this jersey click with so many riders—from pros who train in it to casual weekend riders—and gave it a few refinements so it feels and performs even better.

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.

Lightweight and breathable, Assos’ style-savvy Uma GT SS jersey offers a host of details that render it both high performing and ultra comfortable. Cut in Assos’ new women’s specific regularFit, this moisture-wicking cycling jersey is a little less compressive than their race-tuned apparel but still well suited to both long rides and mid-ride coffee stops. It features triple ramp pocket construction to keep your essentials secure and your mind at ease while riding hard. And, it’s constructed with Dual Tex to meet the demands of the hardest climbs with its low weight and breathability so you can rise to the occasion on every ride.

Named after the movement of color, transitioning from vibrant tones back to ASSOS black. This is Shifter, the second generation of Assos' MILLE SS platform, set apart by its comfortable raw-cut sleeve construction, classic regular fit, and limited-edition graphics. From pros who trust it for training to casual weekend riders, it redefines the standard, every-ride jersey.

Building on an every-ride staple for countless riders due to its regular fit, comfortable textiles, and unmistakable ASSOS style, this is UMA 2.0. It’s back wearing a more comfortable raw-cut sleeve construction, its classic regular fit, and bold “psychedelic-lava” colorways inspired by LP cover art from the mid-to-late ’60s.

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.

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

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 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. 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.

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

The EQUIPE RS S11 features an all-new textile on the sleeves, which is lighter than the previous sleeve textile without compromising on the compressive, second-skin fit. The new material is also textured for aerodynamic gains while in aggressive riding positions, reducing drag on the body’s leading edge. The main body of miniCheck Tex is the same as the predecessor, providing ultralight, ultrabreathable comfort and body-wrapping, compressive support, and it’s anchored at the rear hem by the new PILtec Plug-In technology, which pairs an ultralight strip of textile with silicone microdots to stabilize fit while climbing, sprinting, or cornering – even while wet.

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.

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

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 lightest, most breathable ASSOS bib shorts to date. Engineered specifically for full-gas efforts in the hottest conditions—indoors and out—the 120-gram SUPERLÉGER is built on our S9 platform using hyperlight textiles for unmatched stability and boosted ventilation. BEHIND THE PRODUCT To not only reduce weight, but also increase rider comfort and support during the hottest racing days and flat-out indoor training sessions. We reduced the number of seams and replaced current panels’ textiles with hyperlight, more breathable materials to further reduce friction and keep the leg muscles cooler and fresher, for longer durations.

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.

For those days when you're not racing the clock but simply clocking the hours in the saddle. You want to be comfortable and look good. We engineered everything but speed into this jersey. It uses a brand-new fabric that lets us cross-dye it to give a richer depth of color to the shoulders and sides on an otherwise solid-colored jersey.
