Castelli Nano Flex 3G Armwarmer
The Castelli Nano Flex 3G Arm Warmers are a stalwart of your winter cycling kit rain repellent, windproof, warming and luxuriously comfortable, this latest evolution of the Nano Flex technology is Castellis best yet.
The Nano Flex 3G fabric used across these arm warmers utilises a combination of newly updated durable water repellent (DWR) treatment and mechanical heat treatment to give previously unheard-of levels of rain protection. Light rain beads off the fabric, keeping you dry when those inevitable rainy spells descend.
On the inside of the Nano Flex 3G fabric, a super soft finish and the optimal loft have been achieved through Castellis meticulous research and development. The fabric feels phenomenally comfortable against the skin and the loft traps just the right amount of air above the skin to keep your heat regulated over a wide range of autumn and winter conditions.
This latest update to the Nano Flex fabric not only reflects Castellis ongoing commitment to offering you the very best garment quality but crucially means more time enjoying yourself on the bike.
The flat-lock stitching and single-seam construction keep the profile of the warmers low and the stretch is optimised for maximal freedom of movement. A dual-sided silicone gripper at the upper end secures the warmers in place. The compact size of the warmers makes them easy to stuff into rear pockets when conditions lighten up.

Paired with Perfetto alpha light or Gabba it makes ideal kit for cool days with wind and showers. Great item. Typical top service from ProBikeKit.
They do exactly what the say they do. Keep the cold wind off my arms. Slightly thicker than others and do not stretch as well as others, but grab yourself the correct size and that is not a problem. Sixing is correct.
Very good product, kept me dry and warm when caught in a rainy windy ride. Could possibly breathe a little better, but that might compromise the water proofing barrier. Very happy with the product.
I purchased a small size as my arms are quite thin but these are still extremely snug. The material is awesome and very water proof. I ran them under a tap to test them and water just beaded off them and left them bone dry. The advert reads that these are not waterproof but I can tell you that they are!. Look and feel is amazing and great value for money. I have also purchased the nano flex 2 bib tights which are just the same. Winter and rain is no longer an issue. Delivery was super fast. Will definitely purchase from pro bike kit again.
