I use an UA coat... it's GREAT. Super lightweight, thin and warm. I do also wear an UA hoodie as an extra layer to get some extra warmth as the coat by itself isn't quite enuf. Mine is a longer length jacket so it covers low... nice for when sitting on the ground, doesn't pull up on the back letting wind or snow in.
Not typical boarding brand... so I may look like a bit of a poser out there... but I'm warm and dry so everyone else be damned. LOL.
