Shirt and pants have Microsuede outer fabric with Windstopper Supprescent activated-charcoal lining. Pullover is fleece with the same lining. Shirt, $119; pants, $119; pullover, $129. The benefit of this scent-control system is that the activated-charcoal is bonded into the Windstopper lining; you get a two-for-one deal that results in less bulk. The lining does create a little rustle. Get the head cover and gloves, too.
