Seabird Plus vest specifically designed for kayakers. The vest has a zipper and a buckle, so securing it after putting it on is easy. Can be personally adjusted thanks to the adjustable section on its sides. The vest was designed not to move or slip in a seated position, so it doesn’t disturb the user. The sides are made of a thin elastic material in order for the vest to allow free movement at all times. The vest belongs in the PDF group, so it isn’t officially a lifejacket.
