TL600 Exercise Base
This one was designed for an active person that works-out, jogs, swims, 'plays hard' or is involved with any type of strenuous physical activity. The center is ILace for strength and durability. 3/4" poly surrounds the ILace and provides a smooth surface for glue or tape so you get a solid attachment that will last through hours of sweating and hard workouts. It has a 1" French Lace front to give a strong and realistic hairline.
