Main Features

SyPrene SmoothSkin with Nano SCS Silicone

The Synergy Endorphin Quick John features SyPrene SmoothSkin treated with Nano SCS Silicone for added strength and super-low friction. The silicone-treated neoprene makes the suit non-porous, producing low friction for maximum glide.

AquaLift Panel

The AquaLift panel promotes superior flotation. AquaLift side panels wrap around the torso to create added buoyancy.

HiFlex Panels

The upper chest panels employ the greatest flexibility ever obtained in SmoothSkin neoprene, providing unrestricted range of motion.

Dual SmoothSkin Neck

The low-fitting, super flexible, and adjustable SmoothSkin Neck Enclosure eliminates chafing and is very comfortable. The neck panel is made from only 1mm thin SmoothSkin, creating a seal that is impenetrable and soft, thus alleviating problems created by other wetsuits such as chafing, general discomfort, reduced blood flow, and inflexibility. The back of the neckline utilizes a high-grade, non-abrasive aqua velcro to ensure maximum adjustability.

Internal Zipper

The wetsuit features an internal zipper for reduced drag and water penetration. The special inside lining absorbs far less water than is typical, keeping the suit light and allowing it to peel off easily in transition.
