The Columbia Sportswear Bahama II LS is a lightweight, long sleeve fishing shirt featuring a UPF 30 sun protection rating. The Bahama LS Shirt, from Columbia Sportswear, is the perfect choice for a day on the water out in the elements. Constructed from a 100% nylon fabric, the Bahama shirt is extremely lightweight and comfortable allowing full range of motion for the wearer. In addition to comfort, the nylon fabric also offers quick drying capability should you happen to get splashed. The shirt is sufficiently ventilated as a result of dual mesh-lined cape vents at the back shoulders allowing cooler air to enter the shirt and warmer air to be expelled away from the body. Wearing a long sleeve UPF shirt when its extremely hot outside may intuitively sound uncomfortable, but in reality it actually keeps you cooler. Direct contact with the sun warms the body throughout the day and as the body is exposed to direct UV rays the internal temperature actually increases. The shirt blocks the direct rays while also wicking sweat from the body to keep the wearer cool throughout the day of fishing. In addition to simple comfort, direct contact with UV rays can pose serious health risks that can be avoided by simply covering up.Additional features include two big chest pockets which offer plenty of room for small gear and button tabs that enable the shirt's sleeves to be rolled up and secured. We offer the Columbia Sportswear Bahama II Long Sleeve Shirt in four colors: Fossil, Gulf, Sage and Sail in four sizes: M-XXL.
