Washington’s mountains experience a summer drought and a winter monsoon. Between these perfect conditions for climbing and skiing, spring and fall bring persistent storms that deposit large quantities of rain or wet snow during shoulder-season outings, leaving me no choice but to pack a hard shell. Generally, mild temperatures cause me to loathe wearing a rain jacket, as sweat inevitably builds up. I pull on my hard shell when I reach the point where I am getting wetter without it than I will be while sweating in it. Get stuck in rain or wet snow on a long climb with no waterproof layer and, as Canadian guide Scott Davis says, “the forecast calls for pain.” That said, there are days where nothing less than waterproof will work. Despite marketing claims, no fabric is both adequately breathable and waterproof. I thus prefer my shell jacket to be light, compressible, totally waterproof, and able to be worn over a soft shell.
