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).

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.

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.

The GTO straps and leg panels are constructed using our rollBar and one-piece Butterfly panel for proven stability. Each leg panel features our 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).

zeroWaist: A raw-cut, tape-reinforced edge for the smoothest transition possible between the body and fabric panel. More comfort with less pressure.

superFlat X-FRAME: A single section of elastic material—folded over on itself—forming a supportive X-frame that delivers limited vertical stretch in the rear.

skinGrip finish: Raw-cut edge with minimal silicone treatment secures the shorts in place without any excessive pressure.

MILLE GTO c2 Insert: Constructed with our proven stitch-free goldenGate side panels and reversed seams throughout for frictionless comfort. The front section features our new sunDeck superlight—successor to our iconic kukuPenthouse—made using an ultrasoft foam-free textile to form a preshaped cup that both supports the male anatomy and promotes maximum ventilation. The insert introduces our twin21 System made of three separate layers:

microShock: 11mm of lightweight foam creates the foundation of the insert, relying on its proven shock-absorbing composition.

filterFoam: 10mm of lower-density matrix foam is sandwiched between the microShock and 3D waffle to fully absorb microvibrations. Open-cell structure exhausts excess moisture.

3D waffle: This patented next-to-skin, 3-layer perforated foam increases breathability and eliminates excess weight.

whirlKrater: Proprietary system of holes, strategically placed to boost air circulation.
