The Scubapro S-Tek Pure System Package is a technical backplate and wing BCD system engineered for divers who prefer streamlined DIR-style equipment configurations and modular setup flexibility. This S-Tek Pure System combines a continuous webbing harness, stainless steel back plate, and donut wing to create a minimalistic technical BCD designed for stability, trim control, and durability in demanding dive environments. The system is offered as a complete kit with multiple lift capacity options, supporting both single and twin tank diving configurations.

The S-Tek Pure harness uses continuous webbing for a customized fit and can be configured in fixed-shoulder mode for simplicity or Extender mode to lengthen shoulder straps for easier donning and doffing. A 3D-formed stainless steel back plate features a curved central profile, softened organic shape, and radiused edges to improve comfort and reduce pressure points. EVO Angle webbing slots promote natural routing that helps minimize abrasion while maintaining stability.

The donut wing is built with a rugged 1000D Cordura outer shell and 500D Cordura inner bladder, forming a durable technical wing designed to handle repeated use and harsh environments. Its rounded profile reduces air trapping to maintain consistent buoyancy distribution, while the elliptical EPDM corrugated inflator hose and K-Style balanced power inflator support controlled inflation and venting performance.
