About this product
When Do the Castelli Nano Flex 3G Arm Warmers Make the Most Sense?
The Castelli Nano Flex 3G Arm Warmers use Castelli's Nano Flex fabric, which Castelli describes as thermal and water-repellent, and breathable. Castelli says they are warm and comfortable in dry conditions, water repellent in damp conditions, and still warm in extreme conditions. Castelli rates them for 46°F to 68°F (8 to 20°C) and for light rain.
They are built with flat-lock stitching with a single seam, and double-sided silicone grippers keep the warmers in place. The Lab carries them in sizes S, M, L and XL.
