The Castelli Quick-Step Alpha Vinyl Pro Team Sorpasso RoS Bib Tights are made for long rides in the widest possible range of conditions.
They feature ultra-stretchy, warm and water repellent Nano Flex 3G fabric, infused with the third generation of Castelli’s nanotechnology fabric treatment. This adds a high level of water resistance, without affecting breathability, softness, stretch or warmth. The fabric also offers a compressive fit that moves with your body, for all-day comfort.
On the thighs and rear of the tights are panels of Nano Flex Xtra Dry fabric, which provide an even higher level of wind protection and warmth, while keeping your legs dry as you cycle on damp roads.
These tights are not only about their composite fabrics, though. Anatomical patterning gives a bend at the knee and the hip, while the seamless bib straps lie flat and hold the tights and seat pad perfectly in place, leaving you free to concentrate on your cycling. Reflective panels will keep you visible too, while YKK® Camlock® zippers at the ankles make for easy on-off and secure closure.
The bib tights use Castelli’s Progetto X² Air seamless seat pad, which features a skin-care layer, two densities of foam and gel pads that work in tandem with your body and saddle, helping them to slide past each other smoothly when required and offering substantial cushioning in the right places.
