Brand new Castelli Nano Flex+ arm warmers for all weather conditions.
The Castelli classic arm warmer has been updated with more flexibility around the bending part of the fabric in the area around the elbow. The arm warmer has also been made a bit more compact while maintaining its original features.
The Nano Flex+ arm warmer is water-repellent and breathable providing great weather protection. The thermal fabric and the fit provide great comfort while the double-sided silicone gripper makes additional warmers stay in place.
Arm warmers provide warmth, flexibility, and comfort on a chilly day. They are designed for days when it's too mild for a long sleeve jersey and you want some early warmth before you build up body heat, or simply for protection against the weather.
