This is the Hollis LX2 12 lbs Weight Pouch Replacement For BC
Features:
Single replacement Pocket for Hollis LX2 12lb Weight System
The LX2 replaces the older LX pocket and is a great evolution that adds weight versatility with an easy-to-use design. LX2 uses a simple pinch and pull buckle, and a large nylon handle on the pouch to ditch or carry the weights.
The pouch itself is zippered and holds 12 pounds total, but is partitioned to isolate weights within the pouch. The benefit here is if you only have say 5lbs in the pocket, the partition will avoid it shifting around during the dive. This system is also reverse compatible to allow use with older Hollis backplates and harnesses.
This pocket cannot be used independent of the Hollis LX2 12lb Weight System
