The challenge - traditional liners are made up of an outer foam-backed fabric, over a dense foam padding. While comfortable, it all but eliminates air flow and absorbs and retains both moisture and heat.
The solution - the 6D Super Cool liner system is a unique perforated outer fabric, (not foam backed), combined with an exclusive open-cell 6D mesh material that completely replaces the dense comfort foam.
The result is a dramatic increase in air flow. Moisture quickly evaporates and air can travel through with little restriction, allowing cool air in and heat to escape. When combined with the 6D Air-Gap, the performance is unequalled.
