I had been looking for an unlined Gore-Tex parka for both casual and when I have to wear a sports coat or suit--something to fall back on when caught in inclement weather. I had hoped to find something cut loose enough to go over a jacket and with an adjustable hood, armpit zippers, and some cargo pockets. If I remember correctly, I found a nice parka at Eddie Bauer (I think it was lined) but it was not long enough to cover a sports coat. So I finally ordered the Frogg Toggs raincoat in black as shown on http://www.froggtoggs.com/separates.htm and had it shortened to just cover a sports coat by a few inches. As the Tyvek used in making these does not dye evenly, there is a variegatedness to the color. Also the pockets are actually reach through slits with snaps. The Tyvek is almost as thin as unlined Gore-Tex and the cut-down parka is not too large in the briefcase.
