White Stag 4-Seasons windbreaker I picked up last year for $12, but it's definitely been a lifesaver this wet spring. The jacket is super light, so I've just been keeping it bunched at the bottom of my Duluth Pack, ready to throw over whatever I'm wearing at the first sight of rain. The jacket is completely waterproof and has unique oily sheen and some nice little details like a hood that zips into the collar. With all the designer windbreakers out these days, and having not yet found the perfect parka, I'm stoked to have found this jacket for cheap.
