Castelli Nanoflex Plus Arm Warmers

The Nanoflex Plus are water repellent arm warmers by Castelli. These arm warmers are made using the innovative Nanoflex material which allows water to simply bead off the fabric. The liner is made from fleece. The rear side of the arm warmers uses Nano Light, which improves stretch and comfort.

Arm warmers are great to have on you in unpredictable weather, as they're easy to put on or take off during your ride. Arm warmers also allow you to enjoy your short-sleeved jerseys in colder conditions.
