The present invention relates to a skin protection device comprising: a flexible cover having a first end and a second end. The cover comprises two sides extending between said first and second ends. The sides comprise seal sections capable of mutual engagement to form a seal. Each seal section includes a surface that is longitudinally serrated or undulating, wherein serration or undulation is provided on both sides of the section, a first female serrated or undulating side and a second male serrated or undulating side which when placed together form a mating pair and the seal. Each seal section is an extrusion as one part with a flat base and a plurality of serrations or undulations, folded and secured around the sides of the cover so that the flat base is in contact with both surfaces of the cover.
