GTO marks the pinnacle of the Total Comfort Mille GT line - with winter flair in the form of the GTO Winter Bib Tights C2. As such, it features the plushest insert, low-volume insulation, and targeted protection which combine to create the definitive regularFit Winter bib tights for the harshest cold-weather conditions. The Mille GTO C2 pad is engineered with the most responsive multi-density insert offered to date. Friction and excessive pressure on long-distance rides are a thing of the past thanks to reversed-stitch lines and a radically reshaped insert. The insert is constructed with stitch-free goldenGate side panels and superlight sundeck foam for frictionless comfort. A pre-shaped cup both supports the male anatomy and promotes maximum ventilation without sacrificing weather protection.

Outside the overall qualities and seemingly limitless Assos textiles and proprietary garment construction techniques, the Mille GTO Winter Bib Tights C2 also have a very special feature. To engineer the first impact protection-oriented winter bib tights, the design team at Assos developed the IMPACTOR construction using a two-layer system that targets the hip panels. First, they adopted their durable ripstop dyneRope textile from the off-road equipment collection. Second, they re-engineered the removable impactPads with a more flexible, breathable design. The result is built-in abrasion resistance, impact protection, and frictionless ASSOS comfort that ensures you’re prepared for winter’s toughest environments.

The main textile of the lower section is the Assos OSMOS Heavy which delivers maximum insulation, breathability, and pure comfort with its skin-facing brushed inner surface. The blasenSchutz front panel is made with OSMOS Light and a second overlapping layer of perforated SPHERE Ultra Hole, where “micro holes” in the stretchy membrane-backed 2L softshell maintain added protection from cold wind and road spray. The GTO straps and leg panels are constructed using Assos rollBar design and a one-piece Butterfly panel for proven stability. Each leg panel features their louvreTec construction, which tapers to the exact shape of your legs for a custom compressive wrap. The superFlat X-FRAME transition construction on the back carries a single section of elastic material, which is folded over on itself, forming a supportive X-frame that delivers limited vertical stretch in the rear for a better overall fit and support.

Keeping the transitional zone from upper to lower sections to the most minimal build, the designers use their zeroWaist technique, offering the smoothest transition possible between the body and fabric panel. The result is more comfort with less pressure and virtually no skin irritation. Down on the outermost layer of the lower legs, Assos applies their waterBarrier system, a more flexible, lighter neoprene type material called Geoprene. This fabric will shrug off road spray or puddle water and also adheres well to booties for better overall weather protection.

Assos regularFit was designed with greater size and body type flexibility than their raceFit. It is still conforming and adheres to general European sizing, but the OSMOS fabric does have great stretch and compression for varying leg muscularity. Overall comfort is beyond exceptional, making long rides in the cold of winter not only bearable, but enjoyable. The ergonomic pedaling action is supportive and free, as the fabric aligns with your body throughout the motion, doesn't bunch up, and helps encourage blood circulation.
