Most cycling happens outdoors. You know what else happens outdoors? Weather. A cycling jacket or gilet is a must if you don’t want to be sent packing each time the skies turn grey.
These jackets and gilets are designed to fit properly on the bike, often with an emphasis on breathability as well as water resistance. Many can also be rolled up small enough to fit in a jersey pocket so you’re prepared for a sudden downpour or can strip off after an early start.
