The D7 Evo introduces a patented soft wrist ring system for an improved fit, featuring a smart, narrow design with replaceable silicone seals that do not require sewing to the suit's arm. Its lightweight system includes a visual indicator for correct fitting, ensuring it is watertight. Additionally, it is equipped with the SI Tech Quick Neck System and valves.

The suit also incorporates a flexible YKK Aquaseal Plastic drysuit zip for easier donning and doffing. Material enhancements include Nylotech with Kevlar reinforcements and an extra zip pocket for storing dive tables, checklists and more.
