When the conditions are cold & changeable, cycling leg warmers are your best friend on the road, offering much needed weather resistance and warmth right where it's needed, and the Castelli Nanoflex Leg Warmer is a great example in this genre.

Offering a wind resistant outer is pretty standard, but for the Nanoflex Leg Warmer, things get really interesting when it starts raining and its water repellent properties come into play. Whilst not full-on rain proof, they will repel showers, which on fast descents or long stretches far from home, can be a really handy feature. Smooth, stretchy and highly breathable, they are great in every ride condition. A silicon top gripper completes the warmer.

    Sweet leg warmers! Have had no issues so far with these over a couple of months of commuting. The water resistance is ideal for the wet roads and light drizzle. They don't let you overheat either. Really comfortable, great product.

Castelli apparel used to size small small, but over the last few seasons they have restructured their size set for a more international rider base. Therefore, please follow the sizing chart with confidence, but if in doubt, then feel free to go up a size if you are looking at a very aero-style piece.
