"The HD version of the Ethix goggle strap is made for the DJI FPV goggles. This strap is equipped with rubbery grips inside the battery holder slot to aid in holding on to those slippery thinner lipos. The overall design is more similar to the original (one plastic) piece slip adjustment design with a 1.5” (38mm) main band with 1” (25mm) side mounting tabs. The side straps have double stitching to prevent the ends from pulling out of the goggle mounts under high tension. The strap sizing adjustments allow for comfortable fitment for all varieties of head sizes and shapes."
