For an all-weather jacket that's adaptable and protective, we're looking to POC's Signal All-Weather Jacket. It features lightweight, durable fabric with Ripstop protection and can easily be folded down into its pocket. But, more than that, it can easily attach to our bike so we're not trying to cram it into a rear jersey pocket. On the inside, a soft jersey finish improves comfort and a narrow fit and longer back give extra comfort on longer rides.
