Allen ULTRX Blocker Features The Allen ULTRX Blocker combo pairs passive earmuffs rated at 23dB NRR with a set of protective shooting glasses giving the shooter both forms of range protection in one purchase. The earmuffs use an over the head design for consistent comfortable coverage during long range sessions and they comply with ANSI S3.19 hearing protection standards. Noise reduction at 23dB is enough to meaningfully dampen the report of most firearms while still allowing range commands and conversation to come through. Pairing both pieces together under the ULTRX line ensures the earmuffs and glasses are designed to fit comfortably when worn at the same time. The included glasses are built from high impact polycarbonate and meet ANSI Z87.1 impact resistance standards with an anti scratch coating adding further durability to the lens surface. An anti fog coating keeps the clear lenses usable even as conditions and temperatures change throughout a day at the range. The glasses also fold down into a compact foldable design for easy storage and transport between uses. Shooters looking for a matched all in one hearing and eye protection set will find the ULTRX Blocker combo a practical budget friendly choice for the range.
