Head protectors are an important part of boxing equipment, and the Twins Special HGL-3 remains one of the most popular head protectors for Muay Thai sparring. Exceptional quality leather is used for the exterior, and an extra smooth white leather is used for the interior, providing a smooth and well-finished feel. All the seams are perfectly finished and very clean cut. The overall aesthetic is simple and clean, handmade. The Twins HGL-3 uses a strong Velcro closure with adjustable padding, as well as a super durable hook and loop closure on the back. The Velcro itself is heavy duty, with a large square providing a large surface area to ensure a secure fit, and it is highly adjustable, opening wider for larger head sizes or overlapping for a tighter fit. The front and back of the Velcro has heavy-duty stitching to keep it from tearing away from the fabric. Extra padding in the chin and cheek area for good visibility while providing high protection.
