The Lens Capsule is durable padded lens pouch, but with a bit of extra protection in the form of molded EVA caps on both ends where the lens is at its most fragile. You can set your lens down with confidence. 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 secure loop at the rear of the Lens Capsule will attach to virtually any waist belt or MOLLE compatible system, as well as to the sides of many Tenba bags. The lid opens with a sturdy YKK zipper, and the interior mesh pocket holds the included Tenba microfiber lens cleaning cloth.
