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.

Too large

Unfortunately the XS was too large for my thin arms. They did seem well made but runs large.

For cooler, wetter days

I use Nanoflex on damp days or when there is rain in the forecast. I think they have a little less stretch to them than the Thermoflex, but they are warmer and provide some nice protection from the wet. 6'-1160 and medium fits me well. They do stay in place nicely despite a little less flex. i may pull them up once or twice on a long rides if i make a stop, whereas the Thermoflex don't budge on me. Or i can just ride through and not worry about them. seem well made, only been through a few washes but no signs of any wear.
