Full-lengths are for the office.

There is something about riding in pants that feels a bit off. Maybe the full-length feeling is too rooted in our daily lives, and inhibits the power of our existential cycling experience? Or it could be that knickers are just really comfortable. The Castelli Nanoflex Bib Knickers take comfort to another level by ensuring a well-fitted warm and dry ride. With a solid, low-temp rating, and water protection, the Nanoflex is suited for riding throughout the winter.

The Castelli Nanoflex Bib Knickers are made from the Castelli exclusive Nanoflex fabric. Nanoflex is a water-resistant version of Castelli's ultra-warming Thermoflex fabric. The transformation process occurs when the Thermoflex fabric is coated with millions of nanofilaments to create a water-repellant surface. Water beads and slides when it comes in contact with Nanoflex, and all the while, the Nanoflex Bib Knickers retain their warmth and wind-blocking prowess. Besides protecting you from rain and snow, the Nanoflex Bib Knickers give you the benefit of having lightweight, stretchy knickers that warm like a light jacket on your legs and fit like you're off to the races. The Nanoflex also features a fleecy inner-lining that traps a layer of warm air on your skin while it wicks away moisture to the quick-drying Nanoflex surface. This process provides a consistent warmth and dryness that you'll appreciate when it's in the 40s. The Nanoflex adds extra comfort by incorporating breathable mesh bib straps and the Kiss 3 pad. The Kiss chamois uses a seamless construction of brushed microfiber to avoid any chafing, and the pad is anatomically shaped to help follow your movements. The Kiss 3 also features a variable density design with more padding where you need it and less where you don't.

The Castelli Nanoflex Bib Knickers are available in six sizes from Small to XXX-Large, and in the color Black.

super itch

  • Familiarity: I've put it through the wringer

These are my second pair of Castelli bibs. Good compression plus good wind stopping ability. My biggest complaint is with the upper material. Extremely rough and itchy. I cannot wear these without a thick base layer shirt under the straps. My first ride in these I thought it would mellow out but that ride was so so painful. After many washes it still is one itchy material. not the quality i expected.
