The Castelli Thermoflex Kneewarmer features extra warm and stretchy fabric, that is also incredibly breathable and has excellent wicking properties.

Thermoflex is a brushed fleece fabric that feels lighter and more comfortable than Castelli Nanoflex treated fabrics making this warmer a great choice for hard efforts in dry conditions.

The double silicone gripper at the top - one inside one outside, grips both the thigh and inside of the short preventing the warmers from falling down, while the cross-wrap cuff at the calf seals out the drafts and resists riding up.

  • Cross-wrap cuff at the calf
  • Double gripper elastic at top
  • Can be removed over cycling shoes
  • Sizes S-XL
  • Weight 94g (large)
