Soft neoprene pouches provide the perfect amount of extra protection for lenses inside a larger bag. The 5x3.5 in. (13x9 cm) pouch will fit a Canon/Nikon/Sony 16-35mm or a Canon 24-70mm 2.8 (with hood reversed) and other zoom lenses up to 5 inches (13 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.
