While sailing through a cold front a few days out, the wind came up suddenly, and I leaped to the wheel. I was wearing my Gill ensemble: Escape Quick-Dry Shorts ($56), Sonar Polo shirt ($42), and Inshore Sport Jacket ($120). The rain started coming down in buckets, and I was underdressed, but I was surprised to find that the mesh-lined tropical-weight jacket was perfectly waterproof-and I would've known had there been the slightest leak-and the hood was more than adequate; the fast-wicking polyester Polo made a good underlayer, and its collar kept my neck comfortable as I watched the rest of the crew tucking in a reef. Rivers of rainwater ran off my jacket and onto my shorts, which, though they got soaked, didn't get at all cold and clingy, as cotton shorts would have. Earlier, in the sunshine, those same shorts had proven cool and comfortable.
