Product Description

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 Castelli’s 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 Castelli’s 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 Castelli’s 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.

Key Features:

  • Newly updated Nano Flex 3G fabric for exceptional warmth, softness and protection from the rain
  • Minimal seam construction for aesthetic versatility and freedom of movement
  • Easily packable into a pocket
  • Highly breathable
  • Optimal temperature range is 8˚C – 20˚C

Occasionally, without notice, manufacturers change product design and/or specifications.

Base Layer Guide

What is a base layer?

 A base layer is the top you wear next to your skin and under everything else while cycling. It’s soft, absorbent and wicks away sweat.

Who needs a base layer?

Anyone cycling for any distance or length of time will really benefit from the extra comfort of a base layer.

What are the choices?

You can opt for a long sleeve base layer in winter or a short sleeve one in warmer weather. Most are made from fast-wicking polyester, but there are also some in warm, soft merino wool or anti-bacterial bamboo.

What should I buy with it?

A base layer is your first line of defence in a layered clothing system, so it’s best with a jersey as a mid-layer then a windproof or waterproof outer shell for full weather protection.

Anything else?

Base layers are simple and essential, but you can get some really technical options too. There are some with silver woven in to make them more resistant to odour and compression base layers which are said to help muscle recovery.

See our Layering for cyclists guide for more.
