"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® 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."""
