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.

The GTO straps and leg panels are constructed using Assos’s rollBar and one-piece Butterfly panel for proven stability. Each leg panel features Assos’s louvreTec darted construction, which tapers down the outside of each thigh for a custom, compressive hold. The GTO has two leg lengths: STANDARD and LONG (+3cm vs standard).

Featured fabrics

The shorts’ primary textile is OSSIDIA, striking the ideal balance between frictionless comfort and muscle-supporting compression. Its warp-knit composition is made with ultrathin, elastic yarns for muscle hold, breathability, and a silky-smooth wrap along your low back and thighs. The front panel is made with LOSANGA, a new ASSOS-developed textile that eliminates pressure against sensitive areas.

Assos: measure the narrowest part of your waist, then factor in your height; use the fullest part of your hips as a third reference. Assos apparel is cut to mirror your body on the bike — it’s normal to feel bib straps and fabric pull while standing; in the riding position the garment clicks into place.

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

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 Assos’s new frictionless, wrinkle-free paneling. The GTO has two leg lengths: STANDARD and LONG (+3cm vs standard). With large-muscle support, friction, and excessive pressure remaining critical issues on long-duration rides, GTO destroys conventional bib short construction formulas. Assos 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.

The shorts’ primary textile is OSSIDIA, striking the ideal balance between frictionless comfort and muscle-supporting compression.
Assos temperature range: > +21 °C
