This is without question one of the lightest but warmest jackets on the market. I have Marmot Plasma Parkas which are great for the really cold weather. The Rab Infinity was a good choice for cold weather too but without the bulk. The material is super soft and durable. There is plenty of room to move and the hood is very handy. Such a great buy that I now have two!
