Simms BugStopper® Pants with InsectShield® thwarts insects on contact. Wicking, anti-odor, and UPF 50 protection join articulated knees and an stretch waist for indomitable performance on and off the water. Welted, zip-secure thigh, cell, and slash hand pockets deliver storage solutions. And self-fabric overlays at hand pockets resist abrasion.
It's late November in PA so I can't rate the insect repellant feature. They do fit well (5'7", 152#) in medium.
