This to put it quite simply is the best jacket I have ever worn. Its a two piece shell - liner combo. Lets start with the shell. Almost completely waterproof, drops just bead off and then the zippers seal when you close them, you could probably jump in a lake and still be dry. Also totally windproof. Durable zippers. The liner is ultra warm, almost feels like its heated sometimes. Jacket itself is super light, looks good (IMO), and super high quality. Worth the price tag.
