The hood and waist cinch up and the cuffs velcro tight. The funky window pocket on the chest works great for ID, so the paramedics can call your mom after you take a Superman into a tree. Behind the window is an iPod pocket that let's you route the buds through the inside of the coat. It's def waterproof but "breathable" might be a stretch. No worries though, I just unzipped the long arm pit vents, and I cooled right down. Although it's well thought out and seemingly well constructed, I don't think I'd give more than a hundred bones for it.
