Premium Performance. Exceptional Comfort. Built to Last.
The Atomic B2 delivers near top-tier performance with a design focused on comfort, smooth breathing, and long-term reliability.
Using the same second stage design as Atomic’s flagship T3, paired with a chrome-plated brass first stage, the B2 offers high-end breathing performance at a more approachable price point.
Why We Like It
Effortless Breathing at Any Depth
The balanced piston design combined with Atomic’s AFC system provides smooth, natural breathing without constant adjustments.
Extremely Comfortable in the Mouth
The second stage design reduces jaw fatigue, especially on longer dives.
High-End Performance Without Full Titanium Price
Delivers performance very close to the T3, but with a more practical, durable first stage.
Smooth Hose Movement
The Comfort Swivel allows the regulator to move naturally with you, reducing pulling and tension.
