The SeaLion BC from SeaSoft comes in just four sizes. But that doesn’t mean it fits just four sizes of divers. With the SeaLion, a diver can actually keep the same-sized BC for a lifetime. For example, the extra-small SeaLion will fit a typical 10-year-old who weighs about 50 pounds, but will then adjust to fit an adult up to 180 pounds. The SeaLion is equally at home in warm, tropical water or over a drysuit and features an integrated retractor, brass gauge clip, dual tank straps, integrated weights and a full component of D-rings.
