What are Jacket BCDs?

Jacket BCDs are incredibly common with rental gear and are what most people began learning diving with.

They consist of an air cell that wraps from the back under the armpits and waist, with usually a few D rings or pocket weight integration.

The benefits to jacket BCDs are that many people feel comfortable diving in them, as this is what they learned in.

They do have some downsides:

  • They aren’t very customizable
  • They give lift in places that don’t benefit trim
  • They can be hard to replace parts on
  • They usually only come in a handful of sizes

Regardless of the downsides, they are very popular beginner BCDs, so we will recommend some popular models below.

Next up is the Aqualung Pro HD.

A favorite of many rental fleets around the world, this simple BCD has lots of features that are useful to any diver.

The device comes with integrated weights with quick release functionality for hard soft or hard weights.

A hard molded handle is mounted to allow for easy carrying or lifting of the jack.

There are also metal D rings on the hips, above the waist, and on the shoulders to allow for unbreakable attachments of other items. There's also knife mounting grommets on the left side.

The clips on the shoulders allow for the unit to be very easily taken on and off. Double zips on the storage pockets mean that it can be opened from either side.

This allows for easy storage keeping the outside of the BCD streamlined.

The jacket comes in six sizes causing the jacket to range between $470-$600.

The Mares Prestige MRS+ is a decently rugged back inflate BCD with integrated weight pockets, a zippered pocket for storage, and several attachment points.

Weight integration allows you to use soft and hard weights instead of a weight belt for quick ditching.

The metal shoulder D rings are sturdy and easy to find with your hands, and the zippered pockets allow space for you to store spools, cutting devices, flashlights, and more.

The shoulder clips make donning and doffing simple and quick, while a chest clip makes sure it stays snug around your shoulders. Includes a solid built-in carrying handle for easy transport.

The BCD comes in between $300-$460 depending on the size you decide to get. The sizes are:

  • XX-Small
  • X-Small
  • Small

What are Back Inflated BCDs?

The next type of BCD we will discuss in this guide is a back inflated BCD.

These look very similar to jacket BCDs but provide lift in better positions on the back instead of around the waist like jackets.

This makes it easier to be in trim, although it is entirely possible in jacket BCDs. Many people find them more comfortable than jackets because the air cell doesn’t squeeze as much when inflated.

Unfortunately, they suffer from many of the same issues as jacket BCDs:

  • They are hard to customize.
  • Hard to replace parts on them.
  • They usually only come in a handful of sizes.

Back Inflated BCDs are almost fairly common, so here are some versions we recommend.

A decently rugged back inflate BCD with integrated weight pockets, a zippered pocket for storage, and several attachment points.

Because of this devices inflatable design, the waist, and chest are less cluttered than a jacket BCD.

Coupled with swiveling shoulder clips, you’ll experience much greater freedom of movement and a more comfortable fit.

Comes with Mares SLS weight integration system allowing you to use soft and hard weights wherever you go. Metal shoulder D rings and some on top of the pockets ensure longevity and are easy to use.

The waist-cinching system is an incredibly simple stainless steel buckle.

No need for bulky cummerbund systems, there’s only a single strap here to pull tight, and the stainless steel buckle will survive any abuse thrown at it.

This takes clutter away from the waist as well, freeing up movement even more. There is a pocket that is unfoldable which allows you to store items when needed, and stay streamlined when you don’t.

The dive knife storage pocket is conveniently placed and well blended into the rest of the fit.

This BCD is very streamlined which is key to any good BCD. The jacket comes in 5 sizes with each costing a different amount ranging between $399-$420.

A rugged but comfortable BCD that has lots of convenient features. The ScubaPro Hydros comes in 9 different colors meaning there's a BCD for everyone!

The harness is made from injection-molded monoprene gel and along with swiveling shoulder clips allows it to conform to the shape of your body, resulting in supreme comfort.

The material of the harness and wing allow the entire setup to dry very quickly, so you don’t have to worry when packing.

You can select and even change the colors of the BCD, and you can also get smaller accessories for mounting items to it such as flashlights and cutting tools.

The weight integrated pouches allow the use of hard and soft weights.

Metal D rings on the shoulder will not break and are easy to use. It provides lift exactly where you need it to stay in trim and is an excellent all-around option.

A rugged but comfortable BCD with integrated weights, many components are replaceable without rebuying the whole BCD.

While style isn't the most important thing when picking a BCD, its certainly a factor.

What's great about this BCD in specific, is that almost every part, including the jackets buckles, can be replaced without messing around with stitching.

What are Backplate and Wing BCDs?

The last type of BCD that we will discuss in this guide is called a backplate and wing BCD (often abbreviated as BPW).

In general, BPWs consists of:

  • Solid Backplate
  • Wing

An easy way to think of BPWs is like a Lego version of a BCD. You build your own depending on what parts you want and where you want them.

Here are some of the most popular BPWs:

This might just be the most highly recommended starter BCD out there.

This BPW is a cheap way (350$) to begin into the world of BPWs. It includes all the main parts that you will need, and you are able to customize things on top of it.

The devices comes with a plate of your choice, cam bands, harness, crotch strap, D rings, and buckle. If you want certain weight pouches, zippered pockets, extra D rings, or anything else for your BPW, you can always add them.

I recommend a small piece of bungee or shock cord to hold the inflator to the harness.

The DGX custom accommodates any typical aluminum AL-80, LP-85, HP-80 or HP-100 cylinders. The device is surprisingly durable, constructed out of 1000 Denier Nylon, and enhanced with urethane- coated 200 Denier nylon.

Several others git only slightly more, and they range all the way to Halcyon BPWs in the high hundreds or low thousands.

Similar to the above package comes with everything you need but a different wing with size choices (27lb and 32lb lift), tons of color options, and free trauma shears or a dive knife as well.

Overall, this is a great option for just 399$.

Backplate and Wing Options

So what are some options to look for in Backplates and Wings? There seem to be a lot of different types. Wing size, plate material, tank attachment, and additions are 4 major things to keep in mind.

For wing size, more lift may sound like a good idea but it can actually taco around the tank to trap gas and add drag. While you are able to calculate (roughly) how much lift is needed, that is outside the scope of this article.

Measured in Lbs/Kg most often, if you are doing ONLY single aluminum tank wetsuit diving in warm water, 20lbs may be enough.

For people who dive thicker suits, steel tanks, cold water, etc, 30-32lbs may be more appropriate. I would not go over 35lbs or so if you feel you need more you may want to look at your weighting first.

Wing lift for double tanks is also outside the scope of this article. Try to avoid using a wing too large for your purposes or ones that use bungee to keep excess material in.

For plate material, there are 3 major types to consider. Aluminum, steel, and composite/kydex. Steel is the heaviest (generally 4-6lbs) and is best for cold water diving where weight is needed for thick exposure suits.

Aluminum is a middleweight (usually 1.5-3lbs) that is good all around, often for warmer waters though.

Kydex or composite plates are usually super lightweights for travel weight restrictions. These are not hard rules, I use an aluminum plate in ice water because it makes me perfectly weighted in my doubles.

There are also fringe cases like super heavy steel plates. Find what works for you and use it!

For tank attachments, you have 2 major options, cam bands only or an STA. An STA is a single tank adaptor, a metal bar that you attach the cam bands too, with screws attaching the bar to the plate through the wing.

Some people prefer the extra weight of the STA, as well as how it positions the tank away from you a bit. The other option you have to make sure your wing will allow it, which is threading your cam bands directly through the plate and wing to attach the tank to.

You must make sure the wing you choose has slots to accept this type of attachment, but I prefer how it holds the tank closer.

For additions, these can include nearly anything you can think of from where you want D rings placed, to weight pouches to storage pockets and more. This is where it is entirely up to you with how you want to set it up.

Common BPW Misconceptions

These types of BCDs are less common with a lot of divers and so there is a lot of misinformation and myths surrounding them. I’d like to address some of them here and of course, you can contact for more questions.

BPW Myth #1

BPWs are only for tech divers or experienced divers.

This is completely untrue, as BPWs work wonderfully for all recreational diving, and even divers without a lot of experience.

I have actually taught many open water classes in BPWs and things ran perfectly.

BPWs are sometimes thought of as only for tech divers because they are required for manifolded doubles and rebreathers which a large number of tech divers use.

That’s part of the beauty of BPWs, that you can use them for ALL types of diving with just a few changes or modifications for each.

For example, going from single to double tanks, you simply change the wing out, without the need for an entirely new system or harness.

BPW Myth #2

BPWs will float you face down in the water

When referring to under the surface, BPWs does help you stay in horizontal trim more than other BCDs, though they don’t do it for you.

You still have to distribute weight correctly. For on the surface, the BPW will only float you face down if you overinflate it or if you are heavily overweighted in the wrong places.

You don't need your entire shoulders out of the water when floating on the surface, just your head, so some people overinflate them and find they get pushed a bit.

If you have the correct amount of air in the wing, you can float easily and effortlessly. I have dozed off a few times in the water while waiting on the surface in my BPW!

Some people also believe that BPWs are highly expensive, and why would they buy one when they can get a jacket BCD for half the price? Well same as jacket BCDs, there are cheap and expensive options.

It’s as cheap or as expensive as you make it, similar to other systems where jackets can cost anywhere from 250$. I’ve seen some Atomic jacket BCDs over 1300$.

BPW Myth #3

You can’t have weight integrated pockets or zip pockets.

You're actually able to get all of these things and more. It’s purely customizable and you’re able to put any weight pockets that thread on to 2-inch webbing, zip or Velcro pockets, and stainless steel D rings.

It can all be moved and changed for absolutely any style personally fits you.

BPWs can be custom fit to any person because you decide how much webbing is in each place and cut it to your exact length. They even sell short and long plates for people who are of different heights.

I do advise a single piece hogarthian harness like what comes with the DGX package, but that is more personal preference, as it makes things easier and more comfortable.

A lot of brands offer “Deluxe” harnesses with clips and things that just complicate things and add bulk, or have plastic clips that can break.

A great benefit of BPWs is that all of the parts are incredibly durable (Hard to break steel D rings, webbing harness, and a metal plate) but if any parts are damaged in any way, you ONLY have to replace that part

This is much cheaper than replacing an entire BCD if the bladder gets punctured, or a clip breaks.


I hope this article helps in picking the right BCD gear for you. Always remember that one of the most significant factors in selecting gear is the price. Most BCDs have similar features, so it is advisable to stay in a price range that works for you while still using a good BCD that provides safety and quality.

Here is a quick video demonstrating buoyancy control with a BCD.
