MK25 EVO 1st Stage Dive Regulator DIN Cold Water Ready XTIS Insulation Delivers Superior Breathing And Ice Resistant Performance Under Extreme Conditions, Durable Open Water Gear For Serious Tech Divers

EVO 1st Stage Regulator: Cold-Water Performance, single unit
✔️ XTIS insulated design boosts cold-water breathing and ice resistance

The EVO first stage is a DIN-compatible regulator built for cold-water and tech diving. It features an air balanced flow-through piston in a chrome-plated brass body to deliver steady breathing, while XTIS insulation protects the inner mechanism from freezing. Anti-freeze protection enhances reliability in extreme conditions, making it ideal for icy oceans and cold freshwater exploration.

✅ XTIS insulation fully protects inner mechanism, boosting cold-water performance
✅ Anti-freeze protection increases breathing reliability in extreme temps
✅ Two opposing high-pressure ports for up or down orientation
✅ Five high-flow and one axial low-pressure ports on a swivel turret for hose routing
✅ External intermediate pressure adjustment enables quick tuning
✅ Chrome-plated brass body with air balanced flow-through piston for consistent airflow

💡 What is a first stage regulator with XTIS insulation best used for in cold water?

Handy for tech divers pushing into icy seas and freezing freshwater, it keeps internal parts warmer and breathing reliable.

- XTIS insulation reduces heat loss and delays ice formation in frigid water
- Anti-freeze protection improves breathing reliability in extreme cold
- DIN-compatible design with multiple ports supports flexible hose routing in demanding dives
