A Backup That Breathes Like Your Primary
The Atomic B2 Octopus is designed to deliver primary-level breathing performance in a backup regulator.
Built with titanium components and the same platform as the B2 primary second stage, this octo is made to be reliable, comfortable, and ready when you need it—without compromise.
Why We Like It
Breathes Like a Primary Regulator
Unlike most octos, this is built on a full-performance platform—making it feel natural and easy to breathe from in a real situation.
Corrosion-Resistant Titanium Build
Titanium components help prevent internal corrosion, which is especially important for gear that isn’t used as often.
Comfortable, Natural Movement
The Comfort Swivel allows the hose to rotate with you, reducing pulling and improving comfort.

Bright yellow front cover and longer hose make it easy to locate and deploy quickly.
