The standard Redech air bladder has a wing shape (wing style) which is characteristic for technical BC's types. In comparison to conventional BC's, it's perfect hydrodynamic shape minimizes the resistance of movement through the water. Retraction of air bladder through elastic stripe that goes through 8 stainless steel D-rings has several features: minimizes the surface of the bladder, thus minimizing the resistance to movement through water, the possibility of getting caught in obstacles in overhead environments, enables quick and even compression of the bladder and reduces the possibility of air being trapped on either sides of the bladder. The even distribution of air is very important for the right balance, correct trimming of the diver and maintenance of neutral buoyancy and hovering. RedTech uses 1000 Anso-tex (ballistic nylon), material that is extremely resistant to abrasion and puncture. Due to the Teflon layer it dries fast, colors are stable and UV-resistant.
