What is Assos’s Endurance Series?

Assos files Mille (men) and Uma (women) in its Endurance Series, which it describes like this: “The complete endurance series. Streamlined regular fits. Ultraplush inserts. Muscle-wrapping thermoregulating textiles.” The series name is on every Assos product page, next to the product’s own 1–5 ratings for endurance, racing and ride intensity.

racingFit or regularFit — what’s the difference?

They’re Assos’s two main cuts. racingFit (Equipe and Dyora) is, in Assos’s fit guide, a close, performance-oriented fit with compressive fabrics for high-intensity riding — compared with regularFit it feels noticeably tighter by design. regularFit (Mille and Uma) is a balanced technical fit with moderately compressive fabrics: supportive without the tight feel of the Racing models. Assos uses the same size chart for both, so the difference is the feel, not the size.

How should I wash Assos cycling clothing?

Assos’s product pages don’t include care instructions, so follow the care label sewn into the garment. Assos sells its own Active Wear Cleanser, made for washing technical cycling clothing.

regularFit

Cut in Assos’s streamlined regularFit for total comfort on long rides. Set-in sleeves increase freedom of arm motion while stabilizing the shoulder panels.

Featured fabrics

The main body textile is AirCell, a new, ultralight circular knit with an open hexagon pattern that breathes, wicks, cools, and even feels like a Racing Series jersey. AirCell’s bistretch qualities provide elastic, body-wrapping stretch horizontally with vertical support. The rear pockets are further supported by the lightweight Stabilizer V11 mesh, cooler and more breathable than the standard GT version. Full-length sleeves of Push Pull maintain a race-inspired silhouette with low-weight, low-volume, highly elastic comfort and UPF 50+.

Raw-Cut Sleeves

Race-inspired construction that eliminates transitional ridges for clean lines and aerodynamics.

Triple Ramp Pockets

Flexible panel “lids” secure and stabilize pocket contents. The pockets’ upper halves are hyperelastic for added capacity, but the lower halves add firm vertical support to prevent sagging.

PILtec Plug-In

The rear hem features a lightweight, ultrabreathable textile band with a microdot silicone treatment that stabilizes the jersey’s back panel and maintains grip while wet.

When to use it

For the standard Summer 1/3 layering system, this jersey is engineered to seamlessly pair with a Summer Skin Layer and the MILLE GT Bib Shorts.

How to measure

Chest: around the fullest part, under the arms. Waist: around your natural waistline. Hips: around the fullest part. Keep the tape snug but not tight.

Description

Assos’s lightest and most breathable MILLE GT LS jersey, is engineered for long rides in the hottest, brightest conditions with ultralight, ultrabreathable textiles and full-length sleeves for UV protection. Assos created it to adapt Assos’s ultimate hot-weather endurance jersey for the brightest, sunniest climates. Full-length sleeves wrap the rider’s arms in UPF 50+ with a lightweight, hyper-wicking textile inherited from the Racing Series line. The body is made from ultrabreathable, ultra-cooling textiles that breathe like racing equipment but are cut in Assos’s streamlined RegularFit. Though the full-length sleeves are UPF 50, the GT body textiles (UPF 15) are so lightweight that Assos recommend wearing sunscreen underneath them.

The main body textile is AirCell, a new, ultralight circular knit with an open hexagon pattern that breathes, wicks, cools, and even feels like a Racing Series jersey.
