"Don’t let a dropping thermometer keep you from enjoying the great outdoors. Our vented Banyan Top Cover easily replaces your bugnet for comfort in cool conditions. The fabric is our proprietorially-designed ARGON 90. It is breathable, yet wind resistant. It helps to keep your body heat in, creating a micro-climate inside your cocoon of warmth. The vent allows the moisture of your breath to exhaust, and also provides a window into the world. The top cover is designed to work with our unique dual ridgeline system and has four openings small enough to keep bugs out while still allowing your ridgeline to be fully functional."
