Excellent quality

Bought this BC for my 16 year old son, two check out dives and he is pleased. The weight pockets are a unique design, takes a minute to familiarize.


Awesome BCD for the money

By Erik W.

 -  Kona, HI, US

This BCD is awesome! Low profile, integrated weight pockets, with three air dumps! It has lots of adjustment possibilities for a customized fit. It is extremely comfortable while walking to shore dive entry points!

The streamlined Pure BCD offers swivel shoulder buckles, smart trim weight positioning and maximum adjustability. A great BC! Great for travel. The Mares Pure SLS BCD is a giant step in the evolution of back mounted BCDs. The first thing you will notice when donning the Pure SLS BCD is the perfect fit. This new level of comfort is achieved via special shoulder pads which are longer, pre-shaped and reinforced, and which work in perfect unison with the lumbar suspension system. This suspension system is inspired by the design of modern hiking backpacks; the system avoids direct contact between the body and the tank support. Bolt SLS BCD features 7 stainless steel D-rings for complete accessory attachment. Made of very tough 420 Cordura material, it will endure any exposure you submit it to and hold up to the test of time.

Air-cell is separated from the harness, resulting in unrestricted freedom of movement. The bladder is equipped with bungee cords that will aid in a low profile when it is inflated and facilitates rapid deflation when dumping air. BCD comes standard with 3 pull-dump/overpressure relief valves, one is incorporated into the top of the Ergo Inflator; another is located on the right shoulder and a third is located on the rear lower right. Activation of the valves are made easy with both the upper and lower right valves coming with pull cords and the valve incorporated into the Ergo Inflator is activated by an internal cable attached to the inflator mechanism. Mares Ergo Inflator the standard inflation and deflation control device used in sanctioned training programs. Intuitive use and secure grip. The Ergo Inflator comes standard with a 3/8" threaded low pressure quick-disconnect hose.

Superbly comfortable and stable back buoyancy BC provides 40 lbs. (18 kg) of lift capacity in size large yet is streamline and weighs only 8.6 lbs. (3.9 kg). Shoulder straps with swivel action buckle design, adjustable chest strap and a waist strap are all equipped with squeeze-style" side-release buckles that along with the adjustable cummerbund provide a custom fit and ease of donning/doffing. BCD provides storage when needed with its roll-down cargo pocket. The Pure SLS BCD has Mares Slide & Lock System (SLS) for weight release. This unique weight integrated BCD provides a visual confirmation of proper weight pouch insertion, so there is no guessing when you do your pre-dive check before entering the water. In addition, the BCD is equipped with smart trim weight positioning for a balanced feel when diving.

The Slide & Lock System (SLS) weight pockets have sturdy zipper closures and are easy to slide into the BCD even when wearing thick gloves. The SLS is the safest system available and come in a weight capacity of 4kg/9lbs. SLS weight pockets will work with block or soft pouch weights.

This product can only be shipped to U.S. addresses.

I Always dive mares

It's not what I originally ordered. After buying a different mares bcd I was emailed and told the no longer had what I ordered and sent me this one instead. It was worth more than what I originally ordered but does not have a cumberbund and the spine isn't the foldable backpack style I originally ordered. The new integrated weight system is nice and it's lightweight.

Replaced my Mares MRS PEGASES

By robert g.

from Lexington, KY, US

I love the integrated weight system of the Mares BCDs. Once I get used to them, I will not use anything else. D rings are placed in good positions to clip in gear to stream line for better buoyancy. Works well on boat dives and shore dives. Drift dives are very smooth with place to clip on SMB.


Open water recreational

By Belinda B.

This BCD works great. It is open and allows for free movement. The balance is also good. Would recommend for any recreational diver.


Excellent BCD!!!

By John J.

from Albuquerque, NM, US

Excellent BCD!!! Pure SLS is well built and high quality. I own the Mares Dragon for teaching students. It is also well built and high quality. My other back inflate BCD was showing wear and required occasional repairs. I was looking for the best back inflate BCD that had all the options I didn't have on my other BCD. A marriage of freedom movement, comfort, function, high reliability, bullet proof construction, w/ tech rich features. I chose the Mares Pure. The Pure works better than advertised. Buoyancy is easily achieved and maintained. The design and fit are perfect. I'm 6' 1", 210 lbs and a large fits perfect. It is streamlined w/ minimal drag, again well designed. The weight pockets positively lock and indicate so. Bottom Line: Mares Pure BCD, Awesome fit, quality, features, dives well, and great price from Leisure Pro!!!!!

By Darin P.

Drysuit diving at 190 lbs. I needed a xl size .this is perfect with many ways to find tune the fit.

By Peter G.

from Stuart, FL, US

Almost don't. Need a weight belt


Love this bc

By Xiaofan Y.

I love this BC which the air bag is on the back and never feel tight when the airbag is full. It is easy to adjust and even I am underwater. I love this bc



By Ely G.

from Maputo, Maputo, MZ

I like it. Fits well. Only complaint is that many dive operators don't have soft weights so I sometimes end up wearing a weight belt too.


Great BCD Buy


This is great BCD, especially for the price. It was delivered very quickly and packaged well. I couldn’t be more pleased with my first buy from LiesurePro!


Eazy Diving

By Paul S.

It is light and comfortable. It takes a while to learn how to insert the weight bags into their pockets and lock them. Overall a 5 star rating is appropriate and fair. For the price, I will definitely without reservation, I will recommend it to others. I already have two individual who requested information about the BCD. Consider it seriously.


Practical BCD

By Felix B.

from Miami, FL, US

Ergonomic design and super comfortable BCD. Bought for my son and lobed it. I which I didn't have one already so that I could buy this one for me.

Questions & Answers

Questions about this item:

Shopper  Why Did You Choose This?
M K  Recommended more than other brands I was considering by fam/frnds.
Tom T  I ordered the BCD in size XXL, and it came with size S (9 pd) weight pockets, which limits me when diving with cold water equipment. LPro lists that this size should come with 13pd L-size pockets. I ordered size L pockets, and they were 2 inches too long to fit. According to Mares, all sizes of the Pure are equipped with S pockets?! So, can anyone who has ordered a M-XXL Pure tell me whether they got L size pockets or not?
Bob N  I ordered the M and got the small pockets. When I ordered replacements they sent the large even though the order clearly said small. They replaced them within a week
YOUSSEF S  Two years ago I bought a size L Pure SLS and it came with size S weight pockets (9 lbs max each)
Eric K  The large looks like the closet match - can someone validate that it will fit me? I'm 6-4, 185 lbs with a 43in chest and 36 in hips. I'm concerned it will be too short, as well as not tighten up enough on cumberbund.
Rick M  I am 6 ft. 175. Chest 42. Waist 33. It fits me perfect. There is ability to loosen it a good bit so you should be fine. I have had mine for 2 yrs. It functions fine
Eric K  Thanks for the note Rick, appreciate the input.
Dee E  I'm 6'0"and 220 46 in chest and 36 waist fits fine. The cumberbund is in the style of a weight belt and is completely adjustable. You should be good to go.
Eric K  Thanks for taking the time to respond, appreciate the input!
