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 in each pocket, and is partitioned to isolate weights within the pouch. The benefit is if the pouch is only partially filed, the partition will avoid the weight shifting around during the dive. This system is also reverse compatible to allow use with older Hollis backplates and harnesses. The LX2 system ships as a pair with two pockets and two internal pouches.
