- a predetermined region (shown by hatching in FIG. 3) including at least a portion of the hood portion 20 and at least a portion of the back body portion 16b and the above-described boundary portion sandwiching the boundary portion between the hood portion 20 and the back body portion 16b. Area) may be formed of one continuous piece of fabric. At least a portion of the hood portion 20 sandwiching the boundary between the hood portion 20 and the back body portion 16b and a predetermined area including at least a portion of the back body portion 16b and the boundary portion are formed of one continuous piece of cloth. Thereby, the vicinity of the boundary between the back body part 16b and the hood part 20 becomes flexible, and the feeling of wearing the protective clothing 10 is improved.
- the predetermined region is formed by joining two or more separate bodies, the predetermined region has a joining portion (for example, a sewing portion), and the joining portion is a back body portion.
- the hatching in FIG. 3 is hatching for indicating the predetermined area.
- the predetermined area is, for example, an area extending from the back of the hood 20 to the center of the back body 16b. In this case, there is no joining line at the boundary between the hood part 20 and the back body part 16b (the part where the gather part 32 is formed). Therefore, it is easy to secure the protection property and the gather portion 32 becomes flexible, so that a decrease in comfort and workability can be prevented.
