The Columbia Silver Ridge Elite Woven Long-Sleeve Shirt builds Omni-SHADE UPF 50 protection into a tight fabric construction, then extends that coverage up the neck with a dedicated sun protection collar. A button-up front and shirttail hem give it the classic look of a hiking shirt, while roll-up sleeves with snap-button tabs let it convert to short sleeves the moment the trail warms up. Vents keep air moving through the body on longer days out. What Our Gearhead(R) Experts Are Saying:"I wipe my sunglasses down on the built-in cleaning patch without breaking stride, and my ID stays put in the interior security pocket even after a full day of scrambling around."
