The North Face Summit Tsirku GORE-TEX Pro Bibs - Women's

I love bibs! They are warm, breathable, very movable (ie, no waistband digging in!), and they keep my butt dry in wet winter weather. Also, no cold drafts or snow up the back, which is a bonus. Side zips on any pair of bibs (like these ones have) are key in order to be able to pee on the fly. No jacket removal required! These have a perfect thigh pocket for my phone, a chest pocket for wallet/chapstick, and gaiters to keep snow out of my boots. Perfection.
