Designed for young adventurers, the green and blue Bresser 6x21 Roof Binoculars from Explore One are sized for people with smaller hands and faces. They have a slip-resistant rubberized body with a large center focusing wheel. The roof prisms keep the tubes narrow, providing ease of use for both small and large hands. Fold-down rubber eyecups enable them to be used with or without corrective eyewear or sunglasses. These binoculars are recommended for children age 4 and over.
