You have an Aqualung Rogue or Outlaw BCD (see SKUs: UDRR or UDROL) and want to change it up a little with a different color bladder. These bladder covers can give you the advantage of standing out in the crowed. Theres even one for instructors so they will be more readily recognized during training session. Easy to install, adds extra layer of protection and are manufactured from the same durable proprietary fabric as the BCD itself. Available in multiple colors and comes with assembly instructions.
