Atomics' custom matte-finish fabric has a different look and feel, making this new fabric unlike any other BC. You will know it is Atomic the moment you see it. Not only does it Look tough, it's built and designed to hold up year after year. Imagine if you combined a fine leather Ferrari seat with a saddle it's like that! Strong double-laminated polyurethane textile material is designed to hold more pressure. This material will handle cycle and burst pressures to failure nearly double that of standard BC materials. After all, your BC supports your tank and regulator, so it needs to be tough. A watershed moment in BC design. Really The Atomic BC1 actually, sheds water like a raincoat. Water does not penetrate the fabric with polyurethane coating on both sides. The exterior coating is thicker to prevent tearing, cutting or leaking. But, the big benefit the BC is virtually dry right after your dive. Yet another Atomic design exclusive. You will be amazed how easy this is to use, and how securely it holds your tank in place. The concept is similar to the bindings on ski boots and snowboards. The ratcheting band quickly adjusts to accommodate a variety of tank sizes and the over-center buckle locks everything tightly in place. Gone are the days of trying to figure out how to weave nylon webbing into a buckle. Just push the molded belt teeth past the ratchet and lock it down with minimal effort. No sweat. It's quick and easy to load your weights in or out of the water like no other weight system can. Two zippered weight pouches hold up to 10 lbs. (4.5 kg) each of hard or soft weights in sizes Small to Large and 14 lbs. (6.35 kg) each in X-Large. The weight pouches glide into the weight pockets under the arms and lock into place with a reassuring Snap." A simple one-handed tug on the handle is all that is needed to release. It's the same principle that has been used for years on our EZ-LOK fin straps. BCD also has rear non-releasable weight pockets that can hold from 6 lbs. to 10 lbs. (2.7 kg to 4.5 kg) depending on the BCD size. Elite high-performance air delivery systems are the cornerstone of Atomic Aquatics. Why shouldn't this philosophy continue to the inflation system of a world-class BC design? No other manufacturer gives you these options with this level of engineering and performance. Dive with the innovatively-designed Atomic SS1? Or dive with a high-performance pairing of Atomic Octo and NEW Ai Power Inflator? Now you have a choice. The Atomic BC1 is designed to be exclusive even the manufacturing involves a custom hand-crafted sewing process and custom binding tape. An insert-molded polyester reinforced belt in the tank band ensures safety.There is also an adjustable cummerbund for added comfort and security. With 3-planes of adjustability you're assured a custom and comfortable fit. The New Atomic BC1 come with an owner's manual.
