Assos Mille GT Summer Bib Short GTS

GTS marks the introduction of the second generation of MILLE—an all-new bib short that builds on the iconic GT shorts’ Total Comfort formula with its plush double-layer insert, fatigue-reducing textile, and revamped fit. Ideal for pro riders looking for added comfort during training to everyday riders seeking maximum long-distance support.

We started by adapting the patterning of our S9 race shorts, using its two-panel “butterfly” lower to smoothly wrap your legs, lock the insert in place as you pedal, and reduce friction with its minimal seams. Above this, its Xbib straps feature calibrated stretch throughout, with the rear section using a single strap to form an A-frame for added stability.

The OSSIDIA textile—developed specifically for the MILLE GT c2 platform—strikes 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 fit that results is a more responsive, compressive regularFit, ideal for a variety of body types and riding styles.

The heart of the GTS is an all-new insert, adapted from the GT using a double-layer memory foam construction and honeycomb topsheet. This multi-layered cushioning system provides targeted dual-density structural support for your sit bones, while the 3D top layer and kraterCooler ventilation holes increase breathability for added next-to-skin comfort.
