I purchased the Patagonia Dragonfly Pullover for my dad who is a trailrunner. Since I live in Orlando and my parents in Oregon they came out for Christmas. On Christmas Day we went to DisneyWorld in a torrential downpour for the entire day. My dad put the Dragonfly Pullover on my daughter and she ended up being the only dry person at Christmas dinner. She easily pulled it over her sweater and it never once leaked. Well worth the money, it was shipped quickly, and my dad can stick it in a pocket and take it on any of his 100+ trail runs without it being a burden. Thanks
