Inserting weight is as simple as insert and click. With SureLock, your weights are secure in the BC. Once engaged, the only way to release the weight is to pull on the handle. HP and MP hose routings through the back keep your entire kit low profile thus minimizing drag, The pull down oral inflator is easy to deploy, use and stow. Flat e-valves are very streamlined and effective. They are also one-way which keeps water out, A bladder retraction system is used to pull in the sides of the bladder during deflation. This keeps unit streamlined and reduces drag. An adjustable chest strap can be raised or lowered on a rail system. This not only ensures a good fit but also keeps strap from running across top of a drysuit valve.
