Nano Flex 3G Arm Warmer

Rain or shine, wet or dry, these warmers give you the extra bit of warmth you need to stay comfortable when you're riding on a brisk day in early fall or late spring. The stretchy, fleece-backed thermal fabric is coated with millions of tiny nanofilaments that encourage water to bead up and roll off the garment, keeping light rain and tire spray at bay. That being said, the material is also highly breathable, making them a great option for dry days, too.

This used to be one of my favorite pieces of kit and I've been rocking these since the first iteration. Unfortunately they changed the design and removed the elastic band at the wide part of the arm warmer. So now they slide down when I'm riding. A flaw in nearly every arm warmer for tall, lanky dudes like myself. Such a shame. These used to be the only arm warmer that actually fit me, and didn't fall down.

Excellent Warmers

They feel premium and do a great job at keeping my arms warm. As always with Castelli be sure to size up. Worth every penny
