Assos Mille GTS S11 Long bib shorts

A long-distance endurance bib short, engineered to balance aerodynamics, compression, and comfort

The S11 generation is updated with less restriction at the waist and leg opening, increased vertical stability, an ultra-matte finish, and more cooling airflow across the entire dual-layer insert. Available in two leg lengths: standard and long (+3cm). f the S11 changes, the addition of the rollBar suspension system, adapted from the Racing Series S9, is the most impactful. The new construction increases vertical stabilization and allows a less restrictive waist construction. Coverage across the stomach and lower back also increased, providing more supportive, breathable comfort around the waist while accommodating aggressive riding positions. The butterfly-wrap paneling returns for S11, enveloping your muscles in micro-adjusted, fatigue-reducing compression that balances long-distance comfort with competitive aerodynamics. Updated for S11, the latest GTS insert radically increases cooling airflow, and the dual-layer 13mm construction adds 4mm of targeted support to the 9mm base of microshock-absorbing foam.

Featured Fabrics
Volkano is a proprietary textile that faces in with silky-smooth compression and faces out with abrasion resistance, UPF 50+, and a rich, matte black color. Mineral Tec incorporated into the yarns grants permanent odorControl.

Construction and fit
Situated between a pure endurance fit and a second-skin racingFit, the GTS regularFit is our most streamlined MILLE silhouette, providing aerodynamics with long-distance comfort. Available in two leg lengths: standard and long (+3cm).

RollBar
A patented bracing design adapted from the Racing Series. Stabilizes the insert and locks it in place as your weight transfers while sprinting, climbing, and cornering.

PILtec Plug-In
A lightweight, ultrabreathable textile band across the leg opening. The microdot silicone treatment is invisible from the outside but stabilizes fit and maintains grip while wet.

ZeroPressure Waist
A soft, highly elastic waist construction that improves comfort and hold at the waist, minus any pressure or pinching.

GTS S11 Insert
A dual-layer, 13mm construction of fast-drying, high-density foam materials in an endurance cycling platform. One layer absorbs shocks, the other damps micro-vibrations.

3D Waffle
A patented, three-layer, perforated foam that increases breathability and eliminates excess weight.

KraterCooler
Perforations in the inserts' leading edge draw intercooling air to maintain breathability and a dry, cool microclimate.

WhirlKrater
Perforations strategically distributed throughout the insert, creating a whirlwind of cooling airflow instead of just a unidirectional breeze.

GoldenGate 2.0
The insert is attached at front and rear with floating sides and center, letting it move with your body rather than against it. New cut-outs on the sides reduce volume and friction throughout the pedal stroke.

KukuPenthouse
An ultrasoft panel in front of the insert that allows direct aircooling and eliminates pressure, allowing a more aggressive fit across the entire garment.

Composition
Main fabric: 80%PA 20%EA; Padding Insert: 85%PL 15%EA.
