These days, technical fishing apparel comes in all shapes and styles. There’s nothing that says the traditional button-down fishing shirt is de rigueur. There are tons of other looks on the market. Case in point, the Redington Rex Technical Tee.
REI delivers a great little jacket with the Packable Fleet. It’s spare but also extremely light weight. Throw it in your pack and you have an extra layer when you need it. It should be versatile enough for morning runs and other aerobic activities.
