The Super Tidal Long-Sleeve T-Shirt covers the arms through a full day of fishing, and its Omni-Shade fabric holds a UPF 50 rating by blocking UVA and UVB rays. The polyester interlock stays silky and light against the skin, so the sleeves never feel like a heavy layer in the heat. What Our Gearhead(R) Experts Are Saying:"Spray over the side and sweat from a hot afternoon both soak in, and Omni-Wick pulls that moisture to the fabric surface so it evaporates fast. I'm usually dry again by the next drift. The shirt covers my arms and torso, so I still put sunscreen on my face, neck, and hands."
