THERMOFLEX LUXURIOUS FLEECY WARMTH

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.

WHAT IT IS

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

Castelli's advanced Nano silicone is coated on these arm warmers for additional water resistance. Nano Flex fabric provides additional protection from the rain with improved flexibility.

These lightweight arm warmers perfectly protect you from sunburn even on tours lasting several hours. The solar polyester fabric quickly wicks moisture away and prevents overheating. An elastic band on upper end, silicone-screened on both sides, keeps them well in place.
