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.

Warm and comfortable

  • Gender:Male

  • 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

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!

  • Gender:Male
  • 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

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.
