Abstract: A body protection product such as a wetsuit that does not require machine sewing, does not cause discomfort for the wearer, and does not result in a loss to the degree of freedom in terms of design. A plurality of fabric pieces are pressed against each other and joined without stitching to form a three-dimensional clothing base member. An adhesive is applied to the surface of the clothing base member and a stretchable covering member formed of highly stretchable and elastic sheet-shaped fabric is stretched over the adhesive to cover the surface of the clothing base member to match the shape of the clothing base member. The clothing base member and the covering member are compressed under heating and adhered to each other.
