The Libra is the bag for carrying the ballast needed for your scuba diving equipment. It can also carry the weights used by the freedivers. It is made of strong and resistant Denier fabric, for long-lasting use and for a huge weight. Built rugged, the double webbing encircles the entire bag for added strength and joins to form a padded handle. Double-slider zipper makes it easy to access the main compartment. Personal tag or business card compartment on one side.
