If you are looking for a wind jacket you can always have with you then High Coast Lite Anorak is a strong candidate. It can be packed into its own pocket and has all the features you need but nothing unnecessary that will weigh you down. Extra-long zipper at the front, generous fit that makes it easy to pull on/off and a hood that provides welcome protection from the sun. A versatile and light companion on dayhikes, and just as useful for biking to work.
