Lap seams are a more durable sewing process that have the advantage of increasing the durability and comfort of underwear. In the overlapping seam, the edges of the two pieces of fabric are folded in the same direction and then sewn together to form a double-layer structure, which improves the wear resistance and stretch resistance of the underwear. This design also helps reduce direct contact with threads, improving comfort and wearing experience, especially for situations that require longer wear, such as sports or outdoor activities.
