Quality garmets have their place. The zippers, stitching, liners, and fit are of considerable quality above your more economic options. The remainder of their claims are largely BS marketing and fanboy pricing. Windproof is windproof, waterproof is waterproof. All of these new technology fabrics with their big claims all have positive and negative qualities. It's always a give and take. They all strive to possess the qualities of good old natural wool but often fall short. While synthetics are far more durable than wool they lack in either antimicrobial properties and or warmth retention when wet. Where as a synthetic may stink after a day or two wool can be worn much longer before smelling, they may have thermal properties similar to wool when dry, but start to lack when they get damp. If they were anything close then there would be no market for breeding, feeding, shearing, processing, and making wool garmets. Wool would be bankrupt. A decent outer layer garment over a quality wool base layer cannot be beat.
