Premium Material: The GOMRVR-designed Quest 3 halo head strap is made of high-quality ABS plastic material, which is lightweight, highly hard, and challenging, significantly reducing the risk of breakage. Adjustable Size: The headband weighs only 268 grams. The convenient gear-type knob can adjust the head circumference at will. The enlarged headrest can also better protect the head, making you more stable and comfortable when gaming. Ergonomic Design: GOMRVR Halo Head Strap features a gravity-balanced and distributed design so that the VR Headset's gravity is evenly distributed in different parts of the head, reducing pressure on the face. The contact surface is soft and easy to clean: The head strap contact surface is made of soft sponge and triangular leather, which increases friction. The soft leather surface makes the pad very easy to clean without worrying about sweating while playing. Accessories for Quest 3 VR Headset: Please read the user installation manual before use.
