Best Running Top I've ever had
I've been running for about 45 years so I've had a lot of different tops and jackets for inclement weather. This is the best. It's light but extremely windproof and more than reasonably water resistant in rain while not causing condensation or uncomfortable hot sweat. It's also quiet with no strange distracting sounds when you swing your arms. I've worn it in three seasons now simply by changing the weight and type of layer underneath. On top of it all it looks good too.
