Features: It is made of durable neoprene, which makes lifting more comfortable by preventing abrasion and absorbing impact, and can also avoid scratching or cutting of the safety belt. The adjustable headband is technically designed to strengthen your neck and muscles, and bring them to the level that other traditional seat belts can only aspire to. 35.5 inch metal chain and D-type shackle are fully adjustable shackle closure. A size suitable for all sizes of head is recommended for gym boxing and wrestling or rehabilitation. It is recommended to use them with free weight or hook them on the high pulley or low pulley on the machine.
