Keep it simple stupidit! It was confusingly when I started diving so many choices. I researched and looked for equipment I could grow with. Went with the Dive Rite Trans Pac. So glad I did if I want to change things it is very adjustable. I can change out the wing’s, weight pocket’s accesory pockets etc for different types of diving. Add D rings as many any where I want to clip my accessory’s for my preference. Everything is compatible and standard with many different brand’s. If you want the most current style buy it and buy again every time style’s change or your diving skill’s change. Plain black adjustable gear that last’s a long time work’s for me!
