Thermoflex 2 Leg Warmer

Castelli updates their Thermoflex Leg Warmers to make them even more comfortable for those cold weather rides, when shorts are too cold but tights too much. Our legs need to stay warm to pedal most effectively, and the brushed fleece of the Thermoflex 2 keep them insulated against the cold, while wicking sweat away from the skin to keep comfortable. An ankle zipper makes getting the warmers on and off far simpler without removing shoes, while the elastic thigh band keeps them firmly in place beneath our favorite bibs.


  • Versatile leg warmer for cold-weather riding
  • Ankle zipper makes layering on and off simple
  • Top elastic gripper keeps warmers firmly in place for the whole ride
  • Brushed fabric insulates and wicks sweat to keep you comfortable

Not what I expected from Castelli!

I've used it once or twice and have initial impressions
Size Bought:
5' 8"

I needed a new pair of leg warmers to replace some Voler's I had forever and loved. I have several clothing items from Castelli so I decided to give their leg warmers a try. I am very disappointed in these leg warmers. Have only worn them twice and the seams on the thighs are already coming apart. The thigh gripper is not sufficient so they slip down when I am riding. The fit at the bottom of the ankles is too loose so they slip down even more.
