Representing 25 years of breakthroughs and breaking rules, the Atomic Aquatics T25 limited-edition anniversary regulator is a highly evolved version of the iconic T3 all-titanium regulator. To achieve the T25's unparalleled durability and performance, Atomic started with solid bars of titanium alloy and precision machined them to their super-elite specs. But they didn't stop there. To achieve radical durability, Atomic plated the T25's machined body with a new, proprietary diamond-like hardness coating (DLC) carbon nanostructure. The result is a burnt titanium that's stunningly beautiful, ultra-durable and 100% unique. In fact, with its rainbow-like burnt titanium finish, each T25 is highly exclusive-and no two regulators will share the same appearance.
