You never know when a ride is going to get to breezy, but thankfully the Race-Series Wind Jacket packs down small. Stuff it into your jersey pocket and you'll always have wind protection one grab away. Its recycled polyester front offers a sustainable way to fend off wind chill and lower your wind resistance at the same time. And just in case you're worried about working up a sweat while you're boxed up in a windproof shell, don't--mesh back paneling vents away all that warm air with ease.
