Lightweight BCD suggestions?

[Nanight]

I’m currently using a Cressi Air Travel 2.0, which is quite nice, but it adds too much buoyancy when empty (almost 2 kg).

So.. I would like a BCD, back inflated.
Around or below 3 kg in total weight as I travel a lot.
Preferably neutral of negative in the water when empty, as I dive a lot with dry suit and already carry a lot of lead.
Any suggestions?

Anyone has a Cressi Patrol and care to weight it down in water when empty?

I am using a xdeep ghost.
Very lightweight (2.3kg). Not sure if it's neutrally buoyant though.

AL backplate/wing. You may have to replace the wing after 40 years or so.

Xdeep ghost is probably negative, as the backplate is aluminum. It’s generally really nice, but I don’t like their integrated weight system, as the weight pockets tend to hang down a lot from the belt.

and if you go to something negative (s-steel) you can carry less......

A fabric BP/W 'plate' with aluminum buckles and D rings would be the closest to neutral. Without looking at adding padding for its buoyancy to compensate other bits that are negative.

Why absolutely neutral?? As opposed to a little negative being fine?

There are many options for weight pockets from many companies, down to small trim pockets.

A cutout steel plate would be most efficient at low weight that is also useful as dive weight. Aluminum's low density (2.7g/cm3) means only 2/3 of its carry across the beach, or travel, weight is negative in the water. But aluminum components will likely reduce your travel weight.

Sorry, I meant neutral or negative. Didn’t realize there were light weight BCDs that were actually negative. I’ll check in those weight pockets.

Hmm 2.3kg is about 5.07lb. A regular Al bp/w, such as an regular size AL plate, single 30lb wing, DIR type of harness set up including a knife and additional stainless steel buckle on waist strap a at 5.57lb. exactly half of a lb difference, not that much at all.

The surprising part is the harness itself is 1.9lb. the stainless components: 2x buckles, 5x d-ring, 7x triglides; these accounts for 1lb. Webbings and knife are 0.9lbs. if I were to replace all stainless steel to AL components, they will be about 0.4lb. (density of steel 7.6, AL 2.7g/ccm)
then the harness will be 1.3lb, making the while bp/w just below 5lb. This is just for the sake of discussion. I don't think 0.5lb make difference in real life.

This is (probably) true.
