Free your calves.

Eating veal is generally frowned upon, so why would keep your calves all penned up when you ride? Not only are the Castelli Nanoflex Men's Bib Knickers more comfortable than tights—there's something about knickers that just feels right—but they're lined with fleece and made from Nanoflex fabric, which is wind- and water-resistant, so you'll be comfortable all the way down into the 40s. Nanoflex is a weatherproofed version of Castelli's Thermoflex, designed to allow water to bead up and run off so you stay warm and dry. On top, the mesh bib straps stretch with you to prevent irritation and breathe well to prevent moisture buildup. Down below, Castelli's KISS 3 chamois uses a seamless microfiber construction to keep your undercarriage comfortable, and has variable-density padding so you're cushioned where you need to be and have space where you want it.

Great knickers for the value!

I've used these knickers this winter and I am impressed. It stops the cold air from making a difference on the ride and keeps me warm and toasty. I have always worn it with a baselayer so I have never experienced the same problem as the other reviewer had. I got these on sale so I am really pleased. I will buy these again if they go on sale again.


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.
