This next-generation ballast system features an innovative mechanical interference mechanism that activates during insertion, pushing the holding prongs into position and locking them securely. Once locked, these prongs prevent the weight pocket from accidentally detaching, providing peace of mind that the ballast will remain secure. When it’s time to remove the pocket, the system goes beyond simply releasing the interference; it also retracts the prongs inward via a set of sliding surfaces, allowing the male and female buckles to disengage smoothly and without resistance. It includes a large handle and an insertion tunnel on the BCD jacket that guide the ballast pocket directly into place, ensuring the male buckle aligns perfectly with the female counterpart. Designed with a 4 kg weight capacity, the small SLS pocket is both compact and durable, featuring a heavy-duty zipper that keeps weights securely stored. Constructed from high-quality materials, it is built to endure the demands of repeated dives, resisting both wear and exposure to saltwater. Review: Comes in a pair - Had recently lost one of my SLS while traveling north of South America. This came in fast and fitted perfectly (it was delivered bent, but some warm water and weights corrected the position of the insert). Just for mention, I've received a par (two) inserts, the description of the product was not clear if it was a package of two or not. Guess I now have a spare for emergencies. Review: Great replacement - I had to replace my weight pocket as I lost one out of my NEW Mares BC. ( That sucked). So happy I found this replacement. Works perfect. ## Features - ENHANCED DURABILITY - Crafted from robust fabric and plastic materials, these weight pockets withstand rigorous diving conditions, ensuring long-lasting performance and reliability underwater. - OPTIMAL COMFORT - Designed to integrate seamlessly with the Mares Quantum BCD, these pockets provide a snug and secure fit, enhancing comfort and stability during your dive. - ADJUSTABLE CAPACITY - Accommodating up to 9 lbs or 13 lbs (4 kg or 6 kg) depending on BCD size, these weight pockets offer versatile weight distribution for balanced buoyancy control. - SECURE CLOSURE - Featuring a reliable zipper closure, these weight pockets ensure that your weights remain securely in place throughout your dive, preventing accidental release and enhancing safety. - EASY WEIGHT RELEASE - Equipped with a quick-release mechanism, these pockets allow for swift and effortless weight removal in emergency situations, promoting diver safety and responsiveness. - VERSATILE COMPATIBILITY - Specifically designed for the Mares Quantum BCD (SKU: MRSQS), these weight pockets offer a tailored fit and seamless integration, optimizing your diving experience. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B019P2YMFC | | ASIN | B01MXORVPI | | Best Sellers Rank | #303,499 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #88 in Diving Weights & Belts | | Brand Name | Mares | | Capacity | 6 Kilograms | | Closure Type | Zipper | | Color | Not Specified | | Customer Reviews | 4.0 4.0 out of 5 stars (54) | | Date First Available | November 18, 2016 | | Department | Unisex | | Global Trade Identification Number | 00792460218902 | | Included Components | Mares SLS Weight Pocket | | Item Weight | 0.2 Kilograms | | Item model number | 41796 | | Manufacturer | Mares | | Manufacturer | Mares | | Manufacturer Part Number | 0792460218902 | | Manufacturer Warranty Description | This product comes with a full manufacturer warranty. | | Material Type | Fabric, Plastic | | Model Number | 417960 | | Number of Compartments | 1 | | Pattern | Solid | | Pocket Description | Stash Pocket | | Product Dimensions | 12.2 x 10.3 x 2.6 inches; 1.25 Pounds | | Shell Type | Soft | | Size | Large | | Sport Type | Scuba Diving | | Strap Type | Adjustable | | UPC | 792460218902 | | Unit Count | 1 Count | ## Product Details - **Size:** Large - **Sport:** Scuba Diving - **Brand:** Mares - **Closure Type:** Zipper - **Strap Type:** Adjustable ## Images ![MARES Unisex Adults SLS Slide and Lock Ballast System | Robust Zipped Pocket, Easy to use with Thick Gloves | Small Size with 4 kg Capacity - Image 1](https://m.media-amazon.com/images/I/715Dt-c6eSL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Comes in a pair *by R***O on April 13, 2025* Had recently lost one of my SLS while traveling north of South America.
