Description

Nano Flex 3G Knee Warmer

Castelli was an early pioneer of water-protective thermal fabrics, having recognized just how beneficial they are for cycling applications. Don't assume these knee warmers are exclusively for rainy rides on wet roads, however, as the water-repellent fabric is also highly breathable, making them a great option for cooler dry days, too. The best part is if the sun comes out, you can easily slip them off and stow them in a jersey pocket, unlike knickers and full-length tights.

  • Knee warmers that work well for both wet and dry conditions
  • Nano Flex fabric keeps you warm and dry throughout the ride
  • Breathable construction prevents clamminess and overheating
  • Single, flat-lock seam ensures maximum comfort
  • Double-sided silicone gripper keeps the warmers in place
  • Easy to take off and stow in a jersey pocket if things warm up
  • Recommended for temperatures ranging from 54 - 68-degrees Fahrenheit

    Nothing bad to say about these - fit is spot on, warmer than my Pearl knee warmers, snug, stay in place. I'd buy another set in a heartbeat.

    What a garbage product. Pulled them out of the wrapping & put them on to ride & the fabric came unattached from the gripper. This is my last go around w Castelli, the quality is non-existant with their products now.
