The HG-700 features a one piece rubber construction with a secure five point head and neck harness. It's unusual flat disk eyes make this mask especially suitable for use with tint or black out films. The nearly symmetrical design features a downward facing connection port compatible with all 40mm (NATO) hoses and filters.

The striking rubber design (making minimal use of plastic and metal) is derived from the Israeli Model 4 mask which in turn owed its iconic looks to the the much older Dräger Simplex which dates back as far as the late 60s.
