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

The epitome of Assos’s regularFit, engineered for total comfort on the longest rides. The GTO model is upgraded with Louvre Tec to ensure an elegant, streamlined, and wrinkle-free fit in and out of the saddle.

Featured fabrics

Sens Air is lighter and more breathable than the previous generation’s main textile, though it retains the ultrasoft next-to-skin feel while providing UPF 50+. The ultralight Stabilizer V11 back panel extends support up to the shoulders, eliminating pocket sag and wag, even when fully loaded.

LouvreTec

Set-in sleeves and strategic darting at the collarbones and across the back remove excess material, eliminating bunching or wrinkling in the riding position

zeroSeam Pockets

A clean, seamless pocket construction that secures ride essentials with the Triple Ramp Pocket design

Secure Storage

An additional zippered pocket for keys and personal effects

Reflective

Diffusor valves and a central rear stripe provide 360-degree reflectivity to increase visibility in low-light conditions.

Description

The pinnacle of endurance luxury, re-imagined for the next generation with a lighter, more breathable body textile and a simplified, more stable pocket construction. Reduced weight, increased cooling, improved storage capacity – those are the critical changes to the newest GTO Jersey. The new body textile, Sens Air is much lighter and much more breathable, and Assos still deploy Louvre Tec on the shoulders and back to eliminate any excess material that can bunch or wrinkle in the riding position. The pocket updates support long rides with increased stability, supporting increased loads of CO2, fuel, and hydration powder packets for fewer stops and more time in the saddle, and an additional zippered pocket on the jersey’s side adds space for personal effects separate from ride essentials. The jersey is also now even softer against the skin, offer body-wrapping support that eliminates friction.

Sens Air is lighter and more breathable than the previous generation’s main textile, though it retains the ultrasoft next-to-skin feel while providing UPF 50+.
