TOUGH, RELIABLE, ECONOMICAL

It's the perfect go-anywhere reg for both new divers and veterans who like to keep their diving simple and fun.

For decades the classic downstream piston MK2 has been diving's go-to workhorse first stage. It is reliable, easy to use and won't put too big a dent in your pocketbook, and now it's more versatile than ever.

The new MK2 EVO comes with the patent-pending Extended Thermal Insulating System (XTIS) that lets you enjoy an ultra-fast breathing response and maximum airflow with minimal effort -- regardless of how cold the water is. The XTIS makes this possible by fully isolating the mechanical elements of the first stage from the cold, increasing freezing resistance by an average of 50 percent over the current MK2.
