Soft neoprene pouches provide the perfect amount of extra protection for lenses inside a larger bag. The 3.5x3.5 in. (9x9 cm) pouch will fit mirrorless zoom lenses or DSLR prime lenses up to 3.5 inches (9 cm) in length. The quick drawstring closure cinches over the front of the lens without bunching up, and the lightweight design provides protection without being bulky or heavy.
