Thermoflex
With outstanding stretch, luxuriously soft and warm Thermoflex is ideal for cold weather apparel. Fleecy inside traps a layer of warm air next to your skin. High stretch allows for an aerodynamic fit.

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.
