The Castelli Nano Flex 3g Armwarmers provide versatile weather protection, keeping your arms warm in cool temperatures and should rain arrive the Nanoparticle and DWR finish prevents water soaking in.
If you're racing or training in changeable conditions it can be difficult to decide whether to go with a long sleeve or short sleeve jersey. The Nano Flex 3G Armwarmers takes the guesswork out, meaning you get the best of both. For cooler and damp conditions slip them on to provide extra warmth and wet weather protection but should the clouds break and sun show up then they're easy to take off and stow in a back pocket.
This 3rd generation of Nano Flex is better than ever, with extra warmth, a tighter weave and nanotechnology microfilament mechanical water repellent finish combined with a short-chain chemical DWR finish for class-leading water repellency. Castelli's Nano Flex warmers are often copied but never bettered.
