Armed and ready.

Castelli's original Nanoflex warmers were a revolution in water-shedding technology, and now they've made them more compact and more comfortable than ever with this Nanoflex Plus version. It offers the same amount of protection from rain and road-spray, but its multi-panel design uses thinner Nano Light fabric on the backside for better stretch and breathability so you don't have to hold anything back when the going gets tough.

Features double-sided silicone grippers at the biceps. Claimed weight is 69 g / pair.
