3.3kg for travel? yikes that's heavy... easily a full kilo heavier than most of the travel bpw's.
Burhan, look at the hips, that's all you need to see. I can either have a $3 piece of webbing with a metal belt buckle on the end of it as my total harness, or I can have whatever that is with weight integrated pockets, and clips and straps everywhere that cost quite a bit to replace and are completely unnecessary.... Take your pick, but seeing the weight above gives me absolutely no reason to even think about, especially once the cost comes out.
Here is the issue. For $485, I can have a backplate and wing that is made in the USA, to the highest quality standards in the industry. It weighs about 2.5kg for travel, the backplate dries instantly, the wing and webbing are required, but still dry fairly quick. It is truly modular, and you can grow with it in your diving. It also packs flatter because the plate is almost perfectly flat and the wing is easily removable, hell it is designed to come off for travel and cleaning. Should I decide for whatever strange reason that ditchable weight is required, for $50 I can have universal slide on weight pockets for the waist strap.
Alternatively for the same money I can go to a SS BP/W where I can remove 6lbs from my waist strap, and the total rig weight is somewhere around 4kg, but it gives me an instant 6lb distributed weight to offset the positive buoyancy of an AL80 and is usually enough for travel divers to not have to wear any weight at all...
What on earth would compel me to go away from that and go to the hydros?
