Waterproof Breathable Fleece

Unlike most cotton fabric, this sweatshirt won't soak up rain as if it were a sponge. With a water-resistant polymer bonded to its cotton thread, the hoodie repels more than 80% of moisture. And since the polymer is not applied as a coating, the sweatshirt still breathes. Under Armour, around $60 - from Popular Science10/11 p17.
