The Monster Parka from Japanese brand Poliquant is a Military inspired cold weather coat with a few tricks up its sleeves. Insulated, water repellent and made in Japan to the highest standards it only goes and bloody transforms into several different options for you to wear. It can be worn as a classic military look Monster Parka but can also be turned into a shorter insulated jacket. It has a detachable hood so you can also wear both styles with or without the hood effectively giving you 4 jackets in one. Its also got some of those nifty internal shoulder straps so should you get too hot you can hang the jacket off your shoulders for a bit and keep your hands free for other tasks. 

I know I know it's a lot to take in but then, this is a lot of jacket. Check out the pics below to see what we're banging on about.
