Our plushest insert, low-volume insulation, and targeted protection combine to create the definitive regularfit Winter bib tights for the harshest cold-weather conditions.

Behind the product
To engineer the first protection-focused winter bib tights, we developed our IMPACTOR construction using a two-layer system that targets the hip panels. By adopting our ripstop dyneRope textile—and re-engineering our removable impactPads with a more flexible, breathable design—built-in abrasion resistance, impact protection, and frictionless ASSOS comfort is the new standard for winter’s toughest conditions.

Technology overview
The finer details
FEATURED FABRICS

The main textile is our proven OSMOS Heavy, ensuring maximum insulation with its brushed skin-facing side. The blasenSchutz front panel is made with OSMOS Light and a second overlapping layer of our perforated SPHERE Ultra Hole, where “micro holes” in our stretchy membrane-backed 2L softshell expel excess heat, while maintaining added protection from cold wind and road spray.
CONSTRUCTION/FIT

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 construction, which tapers to the exact shape of your legs for a custom compressive wrap.
ENGINEERING

zeroWaist: The smoothest transition possible between the body and fabric panel. More comfort with less pressure.
ENGINEERING

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.
ENGINEERING

waterBarrier: Our Geoprene outermost layer at the bottom of the leg that repels water and adheres to booties.
ENGINEERING

impactPad: New removable, flexible TPU hip pads that have a perforated surface to increase breathability and freedom of movement.
INSERT

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:
INSERT

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

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.
INSERT

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

WHEN/HOW TO USE IT :

We recommend wearing the GTO for your longest cold-weather rides. Layer them under the MILLE GT Thermo Rain Shell Pants during extra cold, wet rides, and pair them with the appropriate jacket for the complete weatherproof capsule.
