The Besto MB is designed for use and easy storage on board passenger ships/ferries on inland waters. This simple jacket was not designed for extended wear, but exclusively for emergency situations. Thanks to the convenient waist strap, the Besto MB 100N is a fast-donning lifejacket: easy to put on and take off. All sizes are designed with Fluorescent Orange High Visibility outer fabric, signalling whistle and reflective material applications for quick recognition and rapid rescuing in case of emergency. Easy to stow as a square package.
