The high-performance winglet buoyancy chamber with its particularly high freeboard and lateral wings ensures optimised turning behaviour of the lifejacket. The ergonomically pre-shaped shoulder area and the compact design ensure optimum freedom of movement. The lifejacket is particularly suitable for long periods of wear, as the neck remains completely free and unencumbered. The head and helmet can be moved without restriction, without the waistcoat hindering the ability to see upwards . With the adjustable and padded waist belt, the lifejacket can be individually adjusted to the user's body size and is comfortable to wear. The practical click fitting, a crotch strap and spray cap preparation are indispensable standards and come as standard. For more active safety, the float also has a pocket to hold the easyRESCUE AIS marine transmitter. The protective cover is also fitted with reflective strips for improved visibility.
