Soft neoprene pouches provide the perfect amount of extra protection for lenses inside a larger bag. The 9x4.8 in. (23x12 cm) pouch will fit a Canon/Nikon/Sony 70-200mm 2.8 or Canon 100-400mm 4.5 (with hood reversed) and other zoom lenses up to 9 inches (23 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.
