The Mares Pure SLS BC Vest is a back-buoyancy vest designed for scuba and diving applications, delivering a stable platform for buoyancy control in demanding dive environments. It offers a back-buoyancy profile with 18 kg lift (40 lbs) to help maintain neutral buoyancy, along with a streamlined silhouette that reduces drag during ascent and descent. The integrated SLS weight system supports secure, intuitive weight management for scuba gear setups.

The vest is designed for comfortable wear under a variety of dive suits. Features like swivel shoulder buckles enhance mobility, while smart trim weight positioning allows precise buoyancy tuning. A roll-down cargo pocket provides accessible storage for small tools or essentials, and the waist strap offers maximum adjustability to fit different body shapes and suit thicknesses. The monoplate backpack supports single or double tanks, making it versatile for different diving sessions and scuba gear. Visual confirmation of weight pouch insertion helps ensure proper setup before entering the water. Personalizable labels on weight pockets aid organization in busy dive environments. The design is customizable and travel-friendly, supporting divers who move between trips and destinations.
