My preference is the inner layer stuff (Their original style product).You have additional versatility because you can wear it under any thing and aren't limited to just cold weather hunting.I don't believe it is the end all,but as part of a regimine it is valuable.The toughest wind to beat is a swirling wind and the buck I shot this year was ona day that was avery gusty day at about 7 yards from the base of my tree.One of my first thoughts was Nah scent lok clothing doesn't work.Long winded answer,inner liner under whatever clothing you want to wear.
