It turns out showers, which on average dump 2.1 gallons per minute, are surprisingly good at simulating some pretty extreme rainfall.ĭuring our indoor monsoon, the Patagonia kept us completely dry, with only a tiny bit of water trickling in from the gap at the neck when we’d look up, and from the cuffs when we’d raise our arms (which was typical of all the jackets we tested, although some were worse and let tons of water in through the neck - more on that below). Since we couldn’t rely on frequent heavy rainstorms to test the waterproofness of our jackets, we hopped in the shower for 10 minutes with each jacket to see if we would stay dry. Whether you’re an avid hiker or just need protection from the rain during your commute, the Patagonia Torrentshell 3L is the one rain jacket you should buy. Your CNN account Log in to your CNN account
