Compact and super comfy, the BCJ-6900 X-Pert BB is one of the most streamlined back-buoyancy BCs we've seen. Starting up front, you'll find virtually no bulk in the chest area. Around back, a three-dimensional air cell with spandex panels keeps everything tidy. Easy to rig, the BC's tank band has a unique cam buckle with a flat spot on it that provides a "half closed" position for a simplified lock-down. There's also a tank positioning strap--always a plus when rigging a weight-integrated BC. In the water, a low-profile inflator and three remote exhaust valves allow you to maintain pinpoint control of your buoyancy. Overall, it's a good all-round BC, and it packs up easily for traveling. $460. www.tusa.com.
