Description of Black Diamond Deluxe Cliff Cabana Double Fly The ultimate shelter built for the worst weather in the vertical world. Fully enclosed for secure weather protection, Deluxe Flys use a waterproof, RF-welded clip in point, conveniently labeled “Wall Side” and “Air Side”, for clipping in to the main anchor correctly the first time. An awning with a moldable copper wire in the brim provides maximum ventilation. Both ledges include poles that easily slide into the built-in guides. For added protection and durability, Deluxe Flys have taped seams and fabric reinforcements along the wall side and on all four corners, which also have generously-sized, reinforced tie downs for securing the ledge in high winds. Keep an eye on the weather through the sewn-in windows.
