Expedition III Long-Sleeve Shirt offers breathable, chemical-free mosquito protection
What Our Gearhead® Experts Are Saying:
"I wore the Expedition III Long-Sleeve on a weeklong paddle trip and didn’t get a single bite. The tight weave really works, and it breathes surprisingly well for how protective it is. I appreciated the zip pockets and fold-up collar for sun coverage too—great piece for buggy trails and warm-weather travel."
We turn to the Expedition III Long-Sleeve Shirt when the trails get buggy and the sun’s blazing. Built by Royal Robbins with Mosquito Protection Technology™ (MPT™), this technical shirt offers chemical-free defense that won’t wash out or wear away. The engineered tight-weave fabric blocks mosquito bites while remaining light, breathable, and soft against the skin—even in humid or tropical climates.
Made from 100% recycled polyester, the Expedition III moves effortlessly with us whether we’re paddling, trekking, or navigating jungle trails. The fold-up collar and adjustable cuffs add extra sun and bug protection when we need it most, and two zippered chest pockets give us quick access to maps, snacks, or travel docs. With sustainable materials and reliable performance, it’s the shirt we trust in warm, wild places.
