SEAC Sub Nick BCD
It is a very comfortable BCD with padding in the back and many options that allow you to customise your BCD. The SEAC Sub Nick allows you to adjust your chest strap's width and height and has special grommets that you can use to attach your scuba diving knife. It also has an adjustable crotch-strap so it won't ride up too much.
The SEAC Sub Nick has a sturdy quick-release weigh-system so you can release your weights in case of an emergency.
The SEAC Sub Nick is a great quality back-inflation style BCD.
