These are no ordinary lens pouches. No longer do lenses have to be put in a square pouch - the Snoot Boot is cylindrical just like a lens. They are also ideal for tripod ball heads as they can be secured to the ball head when it is attached to the tripod or when it"s stored separately. The wide-mouth opening makes it easy to retrieve a lens while the drawstring closure secures it tightly with a spring lock. The Snoot Boot can be attached to a belt or a D-ring of a photo vest so that it"s always available.
