With top insulation properties, the Castelli Thermoflex 2 Knee Warmers will keep your muscles and joints warm for improved performance and less risk of injury on cooler days.

Despite the protection, the fabric remains breathable and minimal seams ensure there's no restriction to movement.

Castelli Thermoflex 2 Knee Warmers

Castelli's Thermoflex 2 Knee Warmers are warm and soft. The fabric is also highly breathable, light and compact, so you can pack the warmers into a jersey pocket when they're no longer required. Minimal seams prevent irritation and allow full freedom of movement in your pedalling. When it's too cold for just shorts, yet you're not quite ready to wear tights, these knee warmers are just the thing.


  • Thermoflex 2 fabric for exceptional warmth and softness
  • Minimal seam construction for aesthetic versatility and freedom of movement
  • Gripper elastic at top
  • Easily packable into a pocket
  • Highly breathable but also insulating
  • Optimal temperature range: 12°C – 20°C
