If you love being on the water and fishing as much as we do...This. Is. Your. Shirt.Gone are the days of wearing an old cotton T-shirt for fishing. With such a rich set of features, Columbia's PFG Force 12 ZERO Shirt will make your fishing trips a lot more comfortable. How comfortable Aside from taking off your sweaty shirt and waving it around for a few seconds and putting it back on (a trick this writer learned from long distance running), and then repeating over and over as the effect wears off, we'll bet your shirt doesn't get cooler as you sweat. This shirt does. It gets physically cooler. This cooling technology, known as Omni-Freeze ZERO, features blue rings that react with your sweat to actually lower the temperature of the fabric. Kind of like wearing an automatic air conditioner, only without the weight.But that isn't the only technology that makes this lightweight shirt particularly effective for long days on the water in search of trophy fish. As part of Columbia's Performance Fishing Gear (PFG) collection, you know you're getting a shirt that's designed for challenging conditions.Omni-WickThis high-performance wicking fabric actually pulls moisture away from your body and enables perspiration to evaporate quickly, keeping you dry and comfortable as the temperature and your activity level increase.Omni-ShadeThis fabric technology blocks Ultraviolet A and B rays, helping to prevent sunburn and long-term skin damage. With the PFG Force 12 ZERO Shirt's ultraviolet protection factor (UPF) rating of 50, you'll be protected all day on the water.Performance FeaturesThe comfortable sun protection collar can be snapped down so it won't flap annoyingly in the wind as you race to your secret fishing hole or you can flip it up for extended coverage of the back of your neck when the sun's behind youAll the seams are bonded to reduce chafing and to give these shirts a really crisp appearanceThe chest pockets feature LightRail Zippers that are more flexible and easier to zip with one hand, plus they almost disappear when closedUnderarm vents and a mesh-lined vent at the upper back provide extra cooling that can really make a difference on hot, humid daysRoll up the sleeves and use the unique, built-in snap
