I love the AK. It is my second coat from Airblaster. It is awesome, super waterproof, really light, and still super warm; once you start moving in it, it will keep all the heat inside so even though it is light you wont need to bundle up like crazy.
Also if you are like me and you like your clothes to fit on you body and not look like you are wearing your dads suit coat when you were five, get a size smaller than normal. 6' 160 and i have a small coat and fits perfect, but like i said I am not a baller so i dont like tight pants and baggy coats, just things that fit nice.
