• Standard Sizing: Built to Fourth Element’s extensive stock size chart (including short, regular, and tall variations), ideal for divers with standard body proportions.

• BioMap® Custom: A bespoke made-to-measure process using 3D body mapping algorithms to build a suit tailored specifically to your unique measurements, optimizing trim and mobility underwater.

Every suit comes with standard factory components (e.g., standard neoprene seals). In the Factory Upgrades section, we provide a $0 Standard / Default option so you can explicitly confirm whether you want the default build or wish to upgrade to premium silicone rings or relief valves.

• Items in Factory Upgrades are factory-fitted directly during suit assembly.

• Items in Accessories & Spares (such as standalone Ellipse glove kits, replacement O-rings, silicone grease, and tools) are uninstalled retail parts and can be purchased individually at any time.

Once your order is completed, our team will reach out directly to schedule your in-person BioMap® measurement session, confirm your boot preferences (HD Boots vs. Neoprene Socks), and verify valve positioning before submitting the build order to the factory.

Custom drysuits typically take approximately 10 to 20 weeks from measurement verification through factory craftsmanship and delivery to Toronto. We will keep you updated throughout the production process and assist with final fit testing upon arrival.
