Wilderness Concepts Gore Tex shirt in deadstock condition from the early 90s. Shirts made of Gore Tex are rare like down shirts, but more so, completely over-engineered for their purpose - hardly anybody bought them because typically you could buy a proper jacket for not much more..........
This one has heavy duty snaps for closure, beefy velcro sleeve closures, and the inner Gore Tex coating is fully intact and definitely waterproof and functional. I found these in a lot and kept two for myself. The design and Wilderness Concepts label graphics look 80s, or earlier, but i am gonna call this 90s due to the Gore Tex label design. This is a small brand unknown to me.
Size is small per the tag and measures 19-1/2 inches across the armpits, 15-1/2 inches shoulder seam to shoulder seam, 24-3/4 inches shoulder seam to cuff, and 29 inches from top of collar to hem along the back.
