Weathermen aren't always correct especially in the mountains, where a warm, sunny day can turn into a chilly downpour on a dime. Just to be safe, carry the Craft Featherlight Vest in your jersey or in your pack every time you ride. It certainly lives up to its name, and it packs into its own back pocket, so you won't even know it's there until you need it. The Featherlight can also be purchased in a high visibility yellow for safety during the day, and reflective trim is included with each colorway for low light visibility. The Featherlight Vest is made with a DWR coated wind and water repellent fabric at the front and an elastic mesh at the back for optimal fit and enhanced ventilation. The vest also features 360 degree reflective trim to make your more visible to motorists and a full front zip for added airflow when necessary.
