Waffle midneck knitted in a unique way using extra-thick yarn. Uses a fluffy and voluminous big waffle material knitted with a special machine that knits slowly at low speed. The main sewing of the body is a flat seam with a flat seam allowance. The sewing part on the skin is flat, so it is very comfortable to wear. The back switch uses a horizontal grain to prevent the fabric from sagging. Due to the characteristics of the material, the fabric tends to stretch during the sewing stage, so slow down the speed of the sewing machine and sew carefully. The cotton material prevents static electricity from occurring and can be washed at home. It is a product packed with ingenuity to be worn for a long time.
