Castelli's Thermoflex 2 Legwarmers provide luxurious fleecy warmth on dry and chilly bike rides in spring, fall and winter.

If you don't need the extra wet weather protection of Castelli's Nano Flex fabric, you'll find that the Thermoflex warmers outpace traditional warmers with a combination of the softest, most comfortable fabrics and the brand's careful attention to construction details.

The single-piece design means the Thermoflex 2 Legwarmers won't rub or scratch while the dual-sided silicone grippers prevent slippage and keep them locked in place.

Features & Specs:

  • Thermoflex fleece fabric is warm, stretchy and soft
  • Single-piece construction with flat-lock seams
  • Embossed Castelli wordmark logos
  • Dual-sided silicone gripper elastic at top prevents sliding down
  • 8-18 Celsius / 46-64 Fahrenheit
  • Weight: 114 g

Keeps my legs warm down to 30F

Unlike my hands, feet, and ears, my legs tend not to get particularly cold. These keep my legs warm in dry desert winters down to 30F. There is a little bit of bunching behind my knees for which I'm subtracting one star, but this is a very minor complaint.

Warmer than one would expect given how thin the material is. Very little impact on leg flexibility

I bike in cold weather with it. There is nothing I dont like

Perfect fit and weight

These fit so well, and I get the right amount of warmth without getting into the heavier thermal territory that is sometimes constricting and too hot. These are perfect
