The Sea Quest Raider BC achieves uniqueness by delivering tech with comfort. For those who have always found it difficult to achieve an exact fit because of having a longer (or shorter) torso, the Raider has a new Torso Adjusting System (TAS). It also features the Self-adjusting Lumbar Support system (SLS), which conforms to a divers lower lumbar. These two features coupled together deliver a whole new level of comfort, custom fit and stability. However, one of the best features of the Raider is the fact that you can quickly adjust the shoulders without having to disassemble the BC - the ease of adjustability and convenience is unsurpassed with this patent pending feature, making the Raider unlike any other BC in the world!
