The Windguard 3.0+ (-WG3-) is our latest improvement to heat management. This new system allows for a smoother more evenly distributed heat as well as better and longer coal utilization. The result is a smoother longer lasting smoke, without burning or harsh aftertaste. As with our first windguard system there is no longer a need for aluminum foil or for coal rotation during your shisha session. Coals that now last 25 to 35 minutes before replacement will now last 15 to 20 minutes longer.
