Royal Robbins

Expedition Pro 3/4-Sleeve - Women's

What Our Gearhead® Experts Are Saying:

"I’ve worn this on humid hikes where mosquitoes are relentless, and the tight-weave fabric really does make a difference—no sprays needed. It’s lightweight, dries quickly, and the mesh yoke helps dump heat on long climbs. The 3/4 sleeves offer solid coverage without feeling stuffy, and the snap front makes it easy to vent. It’s a smart pick for buggy, sun-exposed trails."

When the trail winds through dense forests and the bugs come out in force, we pull on the Expedition Pro 3/4-Sleeve and keep moving. Royal Robbins built this lightweight adventure shirt with chemical-free Mosquito Protection Technology™, giving us a tight-weave barrier that helps stop bites without washing out over time.

Made from 100% recycled polyester, the fabric is breathable, moisture-wicking, and quick-drying—perfect for long miles under the sun. UPF 40+ protection shields us from harsh rays, while a mesh yoke enhances airflow when the day heats up. The split neck collar, princess seams, and shirttail hem create a closer, flattering fit, and roll-tab sleeves let us adjust coverage as conditions change. With a secure zip pocket for essentials, this is the layer we trust for warm, buggy adventures.
