A wetsuit includes an outer layer and an inner layer. The ester groups are selected from the following:a) an aralkyl group;b) a linear alkylether group;c) a polyethoxylated alkylaryl group; andd) a polyethoxylated alkyl group,with the proviso that at least one of said ester groups is selected from b) or d). An adjustable webbing guide connects the generally vertically extending strap to the seat belt webbing; and there is a device for positively locking the webbing guide to the generally vertically extending strap at any one of a plurality of selectable locations on the generally vertically extending strap. This exposure occurs by etching back a portion of the electrically insulating layer using the first electrically conductive material within the contact hole and within the recess as an etching mask.
