Merge is constructed with a soft Swiss lace top, offering a breathable and lightweight wearing experience. The lace base allows airflow across the scalp while supporting natural movement, making it suitable for extended daily wear. At the front, a 1-inch bleached lace hairline helps reduce knot visibility and create a clean, natural-looking transition into the skin. The clear PU sides and back provide added structure for attachment, making application, cleaning, and reattachment more manageable compared to full lace systems.
