An aquatic breathing apparatus includes a buoyancy vest for aquatic breathing. The vest includes a weight-bearing back portion positionable adjacent a back of a user and a front portion positionable adjacent the chest. The front portion includes a support element adapted for removably affixing an air tank thereto. The support element is positioned for resting adjacent a sternum. A buoyancy element is housed within the front portion, and a pair of side straps is provided wherein each side strap is affixable to connect the front and the back portion to respective opposed sides thereof. A system for aquatic breathing includes the buoyancy vest and an air tank and a regulator. The regulator comprises a hose that is connected in fluid communication at a first end to the air tank and at a second end to a mouthpiece. The hose is supported by a second support element on the vest.
