The specially engineered WindStopper membrane not only provides full protection from the wind with a 0 CFM rating, it also stabilizes the microclimate close to the skin by allowing excess moisture to escape while preventing unwanted moisture from coming back in. Emphasis is placed on breathability.
PrimaLoft is a patented ultra fine microfiber blend that is incredibly soft, lightweight and water repellent. PrimaLoft synthetic insulation absorbs three times less water, is 15% warmer when dry and is 24% warmer when wet than the closest competitive insulation. In addition to these impressive thermal properties, PrimaLoft is lightweight with a down-like softness that adds comfort and appeal and makes it highly packable.
