Ultraspan™ 4-Way Super-Stretch Neoprene: Manufactured using an advanced, high-density 5.5mm neoprene with an Ultraspan™ outer fabric layer. This tight-weave material delivers up to three times the stretch of standard neoprene, offering unrestricted mobility and eliminating the stiff, restrictive feel typical of medium-to-thick suits.

Anatomical Male-Specific Tailoring: Cut specifically to follow the contours of the male body, complete with pre-shaped arms and legs, plus ergonomic underarm panels. This pre-bent layout prevents material bunching, reduces water pocketing, and makes kicking and operating BCD valves feel effortless.

Double Water-Seal Wrist & Ankle Cuffs: Features internal wrist and ankle double-seals complete with integrated zippers. These act as a barrier to drastically minimize water exchange ("flushing") while making the suit easy to slide on and off over calves and hands.

Dual-Zipper Thermal & Surface Comfort: Features a rear G-Lock™ main zipper paired with a double-flap water dam to seal out chilly water down the spine. It also incorporates a small front neck zipper with a sealed gusset, allowing you to quickly open the collar for pressure relief on the boat or shore without taking off the suit.

Removable 3D Thigh Pocket: Includes a removable, mesh-bottom 3D pocket mounted on the right thigh for stowing slates, small lights, or a surface marker buoy (DSMB). The mesh base allows water to drain instantly upon exiting the water.

Dive Computer Retention Loops: Built with integrated rubber loops on both forearms to lock your wrist computer or depth gauge securely in place, keeping it in a readable position as the neoprene compresses at depth.
