In less than 15 minutes, unconsciousness would be likely. The best drysuits are custom-tailored and manufactured with custom features. When wearing heavy layers, you still need good range of motion. A drysuit should be light and soft but also durable and flexible. A cold-water hood should be made with supple, stretchy neoprene that seals well on the face. Undergarments must be of a technical variety that will retain insulation…

Scuba regulators are life-support devices. When you use these under ice and in extreme temperatures, it is important to have confidence in their operation. Regulator free-flows are one of the most significant hazards when diving under ice or in very cold water (less than 4°C). The sudden drop in pressure causes the condition as air passes from the cylinder through the first stage. When high-pressure air passes through the first-stage, it hyper-cools the metal moving parts. In a piston reg, small ice crystals can block the piston open, causing more airflow and trapping the piston open, creating a vicious feedback…
