Marmot 3 in 1 jackets are the right choice when late autumn weather makes it difficult to choose what to wear with your wet rain and cold winds. Components, or a three-in-one jacket, are a great choice because it has a warm lining that can be worn separately. The outer jacket is made of a membrane fabric that is completely waterproof and breathable. It will protect you from the effects of the weather and the inner jacket will keep you warm.
