From Filson:

The ideal shirt for early-season hunts.

Our Sportman’s Shirt is built with the strength and utility sportsmen have expected from Filson for generations. Made of ultralight nylon that wicks sweat away from the body for comfort on the move. A blaze orange shoulder overlay aids visibility. Ideal for early-season or warm-weather hunts when blaze orange is required. Button- front and-adjustable cuffs. Knife pleats on rear shoulders for ease of motion. Button-flap chest pockets.
