NANO FLEX LEG WARMER

Note: This item is a Sales Product Sample, so you're getting first-run quality at the lowest price online.  We encourage you to use our official sizing charts above to determine if this product will fit you. There are no additional sizes available, so please order thoughtfully.

This Castelli NanoFlex Leg Warmer is made from NanoFlex fabric which behaves just like Thermoflex fabric in dry conditions, but then provides unbelievable water repellency when it starts raining. Although it's not fully waterproof, but it's the most effective thing Castelli have ever made for keeping you comfortable in all conditions. It's just barely short of a miracle.

Due to the anatomic shaping and lightness, the Nano warmers feel more natural and bunch less than other windproof warmers. The front side of the warmer blocks the wind with StratoLight. The back side of the warmer has super flexible Action PowerLycra fabric. The two panels are joined by flatlock stitching. Silicone on the inside and outside of the warmers keeps your jersey or shorts from riding up on the warmer and reflecting treatments make sure youll also be seen in the dark.

Tech Specs:

  • Windproof front in stratolight
  • Action powerlycra® fabric on back for a better fit, muscle support
  • Flat-lock stitching
  • Anatomic cut for a close fit that doesn’t constrict the rider
  • Silicone gripper elastic to hold the warmer in place
  • Reflective treatment on back
  • Ankle zippers makes geting them on and off over your shoes a cinch
