Ram-air parachutes are a type of parachute designed to provide better control and stability during descent. Unlike traditional round parachutes, they have a rectangular shape and are made of two layers of fabric that create air-filled cells. This design allows them to glide through the air, giving the user more maneuverability and a softer landing. These parachutes are commonly used in skydiving and paragliding because they can be steered and landed with precision. The increased control makes them popular among experienced jumpers, as they can perform various aerial maneuvers and land in smaller areas compared to round parachutes.
