The Castelli Nanoflex+ mark a serious update for the Italian manufacturer's most popular arm warmers.

Combining with the soft, warm and water-resistant NanoFlex fabric, the new Nano Light inserts on the back of the warmer boost stretch, comfort and water resistance.

Castelli Nanoflex+ Arm Warmers

The Castelli Nanoflex+ upgrade and improve on Castelli's most popular arm warmers design. Constructed primarily from NanoFlex fabric, these arm warmers provide light, comfortable and flexible insulation. On top of this comes the water-resistant properties that are more than capable of standing up to a light shower.

New Nano Light inserts on the rear of the warmers provide extra stretch and comfort without compromising warmth or water-resistance. Double-sided silicone grippers keep the arm warmers firmly in place under your sleeves and the wide 0 to 22˚C temperature range makes this one of the most versatile items of clothing in any cyclist's wardrobe.
