What Our Gearhead(R) Experts Are Saying:"This shirt is a lifesaver when I'm hiking or fishing in buggy zones. The Insect Shield treatment actually works-I've noticed way fewer bites-and the fabric stays cool even when it's hot out. Add in the UPF 50 protection and venting, and it's my go-to for full-day sun exposure."When the sun's high and the bugs are relentless, we turn to the Columbia Shoaltech Long-Sleeve Shirt for coverage we can count on. Designed with Columbia's Insect Shield(R) technology, this shirt helps keep biting pests at bay without the need for constant sprays. Paired with Omni-SHADE(TM) UPF 50 protection and built-in back vents, it keeps us cool and shielded through long days on the water, trail, or in the field. This trail-ready shirt includes functional features like roll-up sleeves with snap holders, multiple chest pockets with secure closures, and an interior security pocket for stashing essentials. The soft yet durable polyester construction wicks moisture and resists wear, while a sunglass cleaning patch adds a thoughtful touch for when conditions get dusty.
