Product Information
The Mares Kaila SLS BCD is a She Dives jacket-style buoyancy compensator built for female divers, combining a hybrid aircell with backmount and ADV (adjustable buoyancy) characteristics, a 420 Cordura shell, and an integrated SLS weight system with a quick-release for emergency weight drops.
Who it is for
This BCD is designed around the She Dives fit, with shoulder strap shape and positioning for a woman's build and a shorter overall length. It suits recreational divers who want a jacket-style BCD that stays stable on the surface while offering a cleaner body position underwater, and whose single plate backrest works with either a single cylinder or twin cylinders.
Key details
- SLS (Slide and Lock System) ballast with stable holding surfaces and a quick release for emergency weight drops
- Fusion bladder paired with 420 Cordura fabric for abrasion and UV resistance
- Monoplate backpack suitable for single and twin cylinders
- 5 stainless steel D-rings for gear attachment
- Ergo inflator with a counter-shoulder strap that anchors the adjustable corrugated tube

Frequently Asked Questions
How should a scuba BCD fit?
A BCD should fit snugly enough that it does not ride up toward your ears when inflated, while still letting you breathe fully. Fasten the waist and cummerbund first, then adjust the shoulder straps so the tank sits close to your back and the shoulders cannot slide off. With the BCD fully inflated at the surface you should still be able to take a deep, comfortable breath; if it squeezes your chest, loosen it or move up a size.
How do I rinse and care for a BCD after diving?
Rinse the outside in fresh water and also flush the inside of the bladder, because salt water gets in through the inflator and dump valves. Fill the bladder roughly a third full of fresh water through the oral inflator, slosh it around, then drain it out through the inflator and each dump valve. Hang it to dry out of direct sunlight and store it partially inflated so the bladder walls do not stick together.
Should I use integrated weights or a weight belt?
Integrated weight pockets carry the lead in the BCD itself, which many divers find more comfortable and easier on the hips, while a weight belt keeps the weight independent of your BCD. Either way, you must be able to release your ditchable weight quickly with one hand, and your buddy should know how your system releases. Non-ditchable trim pockets are useful for balance but should never hold weight you might need to drop.
How do I pack a BCD for travel?
Make sure the BCD is completely dry inside and out before packing so it does not mildew in transit. Remove all weights, deflate it fully, and fold or roll it around softer items such as a wetsuit to cushion the inflator and valves. Avoid hard creases in the air cell, and unpack and air it out as soon as you arrive.
When does a BCD need to be serviced?
Follow the service interval in the manufacturer's manual, which is commonly an annual inspection alongside the rest of your life-support gear. Have the inflator, dump valves, and bladder checked any time the inflator sticks, free-flows, feels rough, or the BCD holds air poorly. Between services, confirm that it inflates and deflates properly as part of every pre-dive check.
What is the difference between a jacket-style and a back-inflate BCD?
A jacket-style BCD holds air in panels that wrap around your sides as well as your back, while a back-inflate BCD keeps the entire air cell behind you. Jacket styles tend to feel very stable and upright at the surface, and back-inflate styles keep the chest clear and are often preferred for horizontal trim underwater. Neither is objectively better, so treat it as a fit and preference decision and try both if you can.
Will my BCD fit any scuba tank?
Most recreational BCDs use an adjustable cam band sized for common single-cylinder diameters, so standard aluminum and steel tanks generally work. Re-check the band tension after the first wetting, because webbing can relax slightly and let the tank shift. If you dive doubles or unusual cylinder diameters, confirm compatibility with the manufacturer before assuming it will hold.
Is the Mares Kaila SLS BCD made specifically for women?
Yes, it is built on Mares' She Dives platform, which shapes and positions the shoulder straps for a woman's build, with a shorter length. It uses SLS weight integration, 420 Cordura construction, and a Monoplate backrest.
What sizes does the Kaila SLS BCD come in?
It is offered in five sizes: XXS (2X-Small), XS (X-Small), S (Small), M (Medium), and L (Large), all under Mares model code 417363.
Can the Kaila SLS BCD be used with twin tanks?
Yes, its Monoplate single plate backrest is designed to work with either a single cylinder or twin cylinders.
How does the SLS weight system on the Kaila SLS work?
SLS stands for Slide and Lock System, Mares' integrated weight pocket design that locks the weight pockets in place for stable ballast and increased holding surface while diving. It releases via the quick-release mechanism if you need to ditch weight in an emergency. Correct insertion is visually confirmed before the dive.
