Item # CST009G

A worthy substitute for your favorite bibs.

You can resist giving up your favorite pair of bib shorts for a few weeks, or maybe a month or two of fall, but eventually, your legs are going to need some more protection. If you want a one-piece solution to keeping your lower half warm during cold-weather cycling, Castelli's Nanoflex Donna Tights represent a sleek, highly functional choice. They have a built-in KISS Air Chamois so you won't need to deal with layering, and they are constructed with Castelli's Nano Flex fabric, which wicks moisture quickly away from your skin to manage body temperature. Water beads up and rolls off immediately when it hits Nano Flex, so you won't need a shell with these tights if you're heading out on a day with threatening skies, and Castelli used as little seaming as possible to eliminate areas where water could get into the tights.

Castelli shows its continuous attention to the small details that contribute to a piece of clothing's functionality as well, using Giro3 ankle grippers to create seamless, sealed integration with your shoe covers, and including ankle zippers that make it easy to put the tights on or take them off. As a final touch, reflective accents on both the zippers and the sides of the legs help enhance your visibility as you try to pedal home before those early winter sunsets.

Great fit, comfortable, warm

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs small
  • Size Bought: Medium

Castelli is my favorite and these tights are no exception. They are a comfortable, cozy weight, feel good on, and fit super. I'm 5'5", 115 lbs, with a 25" waist and 35" hips. The medium fit perfectly. I also wear a medium in Castelli shorts. I'm typically a size small but routinely size up for Castelli shorts or tights. Castelli chamois are always comfortable for me, and while a bit larger than some others, it isn't noticeable when riding.

nice warm and snug fit

  • Fit: True to size

For me the size is true, I wear medium shorts/bibs, etc and is true to size. I am 5'6'' weight 135 pounds and have a shortish torso with longer legs. The chamois is not to big and fits well. Have not worn it yet, its not that cold in TX, yet

Stayed (almost)_all dry in the rain

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs small
  • Size Bought: XL

Wore these a couple of days ago in colder weather (high 30s- low 40's) when the weather threatened to rain. Well it actually snowed, and then it rained (light to moderate- not a downpour) ....Water droplets beaded on the tights and rolled off. When I took the tights off, my legs were dry. The only place that was wet was right above the saddle where the constant wheelspray from the rear tire was a bit too much for them. Was glad I was wearing them or surely would have froze descending the canyon. I have also ridden in them in dry weather (temp 40's to low 50s). They kept my legs warm without being stifling, nice for the cold descents, but wouldn't wear them if much warmer. Perfect if the weather is cool and threatening to rain. Would still rely on a truly waterproof pant if downright raining hard.
They run small which is a bit of an ego bruiser--buy one size up.

I purchased these for winter riding in PA. They keep me very warm on high 30 degree days. I usually wear a small in Castelli and thought I would need a Med after receiving them. They were tight around my ankles. I kept the small and they have worked out great.
