I've got a double one that I use for snow sports, but I like using each of the individual layers even more than i use the jacket as one piece. I especially love that the exterior is a great rain coat without the heavy lining for summeresque rain days where its humid and muggy, and I my fleece lining does have an exterior rain-resistant cover so I can use it for the cold dreary rain coming down here that isn't a downpour. Oh, and I have huge love of the massive pockets the exterior coat has and the extra ones on the inside of the fleece liner!
