Castelli Custom Thermoflex Knee Warmers

Thermoflex is luxuriously warm and stretchy in dry conditions but is not intended for wet conditions.

If you don't need the extra wet weather protection of Nano Flex, or if you've always been happy with traditional warmers, you'll find that Castelli's Thermoflex warmers offer the softest, most luxurious fabric combined with careful attention to construction details.
