Now stretchier and more fitted, the Aria 2 Women's vest is the perfect light, just-in-case windbreaking layer. Constructed with a pocket it can pack into, it blocks wind at the front and sides, while a mesh back allows heat and sweat to dissipate, avoiding overheating or chilling when you stop to rest. So insubstantial as to feel almost weightless, with ergonomic shaping, a soft raised collar for protection and reflective touches for low-light visibility, wear it to add a touch of warmth first thing, last thing or during any long downhill stretch.

Bring it on any ride, you won't notice it until you need it.
