People fishing in G4

"As a fly-out fly fishing guide in Southeast Alaska, I spend May through September on the rivers and beaches of the Tongass National Forest. In between the logjams, devil’s club, barnacles, and 100+ inches of rain a year, this harsh environment is where gear is tested to its limits, and that’s why I wear the Simms G4 Collection."
