Patagonia DAS Parka

Simply the best winter parka I've ever owned.  I've had mine for over three years and it still performs brilliantly.  It's light, sheds snow, blocks wind, and stays warm even when it's wet.  It's roomy enough to throw over whatever you're wearing, yet warm enough to throw on over a T-shirt.  Between living in Boston and frequently traveling to Little Cottonwood Canyon, Utah, this is my go to piece.

PS  The DAS has two huge pockets (that seem limitless in size) on the inside that are extremely useful for stashing a neck warmer, hat, wallet, flask, etc.
