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.

Warm and comfortable

  • Familiarity: I've used it several times
  • Fit: Runs small

I'm impressed with these so far though I haven't been caught in the rain yet. They are warm enough so that full tights aren't necessary when the temperature dips to the mid 40s here in southeast Texas. Comfortable pad. I found that these run small. I would typically wear a medium or large but needed an XL in these.

Comfortable and warm

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: XL

I live in south Florida and it rarely gets cold but there are a few days when the temps drop below 60 and I do travel north to ride the mountains of NC. I have only worn these knickers a couple times but they are very comfy and warm. Got them on sale and they are my first pair of knickers, love them. They will be my go to cold weather bibs.

Great cold weather bib knickers!

  • Familiarity: I've used it several times
  • Fit: True to size

These are very comfortable and warm bib knickers. I have worn them in upper 40 degree temps to 68 degree temp and they were still comfortable. Just a little warm at the upper 60's, but as long as you are moving it is still comfortable. I have always worn large Castelli bibs and these are no different. I was riding in damp conditions and the nanoflex did a great job of beading water from road spray. It has a good compression fit and the Kiss 3 chamois was comfortable on a 63 mile ride. I could have easily ridden a full century with no problems.
Definitely a great product and if you find it on sale, it is a must buy. I would definitely buy them again. I did not have any issues with itchy straps.

Great knickers for the value!

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: medium

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.
