I'm not trying to hate on Columbia but after gettign soaked one day after a boat ride in a downpour in Drakes's "waterproof" Wader Jacket I did some research on Waterproof Ratings and discovered that Drake...and Columbia at least at that time Waterproof Jackets are rated to only 10,000 mm Hydrostatic Head...that is fine for light/medium rain but will not withstand the pressure of wind-driven rain or "brush-busting". If you want something that will hold up to those, you need something with a 20,000+ mm rating.....Gore-Tex (Sitka, Beretta) or Toray (KUIU) to name a few. First Lite also claims over 20,000 mm but I don't know the manufacturer of that membrane. Waterproof gear with a high hydrostatic rating will readily advertise it....if you can't readily find it...it is likely 15,000 mm or less.
