What are some of the key differences between the Mares Pure SLS BCD and the Mares Ergo SLS BCD? I’m trying to decide between the two, but I’m not seeing much info on the Pure BCD?
Imran Hanafiah –
Thank you for reaching out, Samantha! We appreciate your interest in our Mares Pure SLS BCD. The two models you’re comparing are both designed with comfort and versatility in mind. One key difference between the Mares Pure SLS BCD and the Mares Ergo SLS BCD is their backplate design. The Pure model features a simpler, streamlined design, while the Ergo model features a more complex, curved design that some divers find more comfortable. Additionally, the Ergo model has a higher weight capacity. Both models share many features, including swivel shoulder buckles and smart trim weight positioning. If you could provide more information about your specific needs and preferences, I’d be happy to help you decide between the two models. We’ve also had other customers find our comparison charts and videos helpful in making their decision.

I recently purchased the Mares SLS BCD, and I’m thoroughly impressed with its performance. I love how it’s incredibly easy to put on and take off, thanks to the swivel shoulder buckles. The smart trim weight positioning is also a huge plus, making it perfect for long dives.
Kenneth Lim –
For the price, I was expecting a bit more in terms of innovation. Overall, I’d say the Pure BCD is a solid choice for beginner divers, but I’m not sure if it’s worth the investment for more experienced divers.

Does the skirt help in improving the movement of the diver during swimming strokes?
Junhao Lo –
Thank you for your question about our Mares Pure SLS BCD. Yes, the skirt of our BCD is designed to assist in movement while swimming strokes. The streamlined skirt helps to reduce drag and improve flexibility, allowing for a more natural and efficient swimming motion. However, we recommend trying out the BCD in person to get the best feel for its features and performance.

Can someone tell me more about the ‘soft bungee’ system on the Mares Pure SLS BCD? I’m not entirely sure how it works, but I’m looking for a BCD with a bit more give – hoping it’s worth the extra cost.
Junhao Lo –
Hello Gary, thank you for reaching out about the Mares Pure SLS BCD. The ‘soft bungee’ on our BCDs uses a soft adjustable webbing to provide flexibility in the middle of the harness. This allows for more comfort and support during dives. The soft bungee system also gives you a bit more adjustability to fit the BCD to your body, which can be especially helpful for larger or leaner divers. The soft bungee is definitely worth considering if you’re looking for a bit more flexibility and comfort in your BCD. We’d be happy to answer any further questions you might have!

I’m still getting used to the Mares Pure SLS BCD, but so far I’m really impressed. The streamlined design is great for reducing drag, and the maximum adjustability has been super helpful in getting a comfortable fit. One thing I’m still figuring out is the best way to secure the chest strap – any tips would be appreciated!
Kevin Tan –
I was blown away by the Mares SLS BCD’s durability and water resistance. I’ve used it on countless dives without any issues. The storage compartment is more than ample for my essentials, and the adjustable buckles ensure a secure fit.
Ryan Tan –
Does using this mask during prolonged dive sessions affect the taste perception of the user?
Imran Hanafiah –
Thank you for your question, Ryan! The Mares Pure SLS BCD is a great choice for divers. However, I must clarify that the product is a BCD (Buoyancy Compensation Device), not a mask. But I’ll do my best to provide a helpful answer. According to various studies and expert opinions, wearing a BCD or a full face mask during dive sessions can indeed affect taste perception temporarily due to the dry sensation in the mouth and the increased respiratory resistance. But this effect is usually short-lived and resolves once the diver surfaces and breathes air again. It’s worth noting that the Mares Pure SLS BCD is designed with comfort and adjustability in mind, which may help minimize discomfort during prolonged dive sessions. If you have any further questions or concerns, please feel free to ask.

Excellent product overall! I was a bit skeptical about the price at first, but after using it, I realize it’s totally worth it. I wish it had a slightly larger storage capacity, but that’s a minor complaint.
Celine Lee –
I’ve been using the Mares Pure SLS BCD for several months now, and I’m really happy with it! The smart trim weight positioning has made a huge difference in my dive efficiency – thank you, Mares!
Evelyn Wong –
I purchased the Mares Pure SLS BCD a few weeks ago and it’s been a game-changer for me! The swivel shoulder buckles have made it so much easier to put on and take off, and the trim weight positioning has really helped with my buoyancy control. The only thing I wish it had was a few more pockets for storage.

How does the SLS system’s design accommodate the varying buoyancy of divers during dives?
Junhao Lo –
Thank you for your question, Brenda. The Mares SLS (Smart Locking System) is designed to provide quick and easy inflation/deflation of the BCD, while also ensuring a snug and secure fit on the diver. The SLS system’s design is meant to work in conjunction with the patented ‘Slide and Lock’ buckle mechanism, which distributes weight evenly across the divemaster or diver’s body. This helps maintain a consistent level of buoyancy throughout the dive, regardless of the individual’s body position or depth.
