The Halcyon Zero Gravity Sidemount System is suited for double aluminium 80’s and a wetsuit or 12L steel cylinders with drysuits. It is ideal for temperate waters but still fun for explorers and recreational sidemount level divers.

Zero Gravity puts the buoyancy over the hips and along the sides of the rib cage where buoyancy is desired. The air chamber positioning gives the Zero Gravity a flat and streamlined profile on the back of the diver.

The streamlined design with a unique U-shaped bladder provides an almost free and clean back that reduces your profile and drag when in the water. The outer back is reinforced against abrasion.

A harness system with multiple point adjustment is styled after the standard backplate harness, with the lower portion of the strap going behind the diver, allowing for greater freedom of movement and comfort, especially for female divers.

Another advantage of the Halcyon Zero Gravity Sidemount System is that it is a small and compact unit which will pack nicely along with other gear for travel.

What stands out

The newly redesigned door handles allow cylinder bolt snaps in a free-moving area to swing without getting caught in the corners.

Two inflator ports on the front, each side of the diver, allow inflator placement on the right or left-hand side of the system.

The OPV placement on the left back side allows for easy location and use while gas is being exhausted.

The adjustable bungees make it easy to use with different regulator configurations, whether the regulator is pointed up or down.

The waist strap d-rings on the right and left hip allow for Ali 80’s to be clipped forward as they become buoyant.

The uniquely positioned cylinder bungees run across the back of the system, giving you more stretch when wrapping your valves while keeping your cylinders high, tight, and secure.
