Get a shirt that will keep you out on the water all day long the Columbia Men's Solar Cast Zero Long Sleeve Shirt. Columbia's Omni Freeze Zero fabric uses small blue rings throughout the shirt that react with your sweat and cool the temperature of the fabric, leaving you more comfortable. Omni shade technology takes the worry of damaging UV rays away, and with the antimicrobial treatment, your shirt will stay fresh so you can wear it the next day without your guide protesting. With anglers specifically in mind, Columbia threw in a few extra bells and whistles. A utility loop can be used clip on a pair of hemostats or floatant, and a rod holder can be used to secure your rod when you're changing flies out. So next time you're out on the water, wear a shirt that is going to keep you out longer.
