Allen's Gamma Junior Shooting Muff & Glasses Combo is sized slightly smaller to fit smaller heads. The ANSI Z87+ impact resistant shooting glasses feature an anti-scratch coating and a wrap around frame for extra protection. The soft temple pads and non-slip nose piece make these lightweight glasses comfortable to wear. The adjustable shooting muffs have a Noise Reduction Rating (NRR) of 23dB, meet ANSI S3.19 and CE EN 352 requirements, and have a soft padded headband and ear cups. The muffs fold down for easy storage and transportation.
