Ergodyne® Skullerz® Dagr blade-frame Safety Glasses have coinjection rubber temples with nonslip tips and a nonslip rubber nosepiece. The clear, scratch-resistant lenses block 99.9% of harmful UV rays. Permanent Fog-Off™ antifog technology won't wash or wear off. The accessory slot on the temple also improves air flow for comfort. Like all the Skullerz safety glasses, this tough half-frame eyewear is constructed with MIL-PRF ballistic impact protection and a lightweight frame.
