The Kirby Morgan band mask 28B, (KMB-28B) is the latest in the band mask series developed by Morgan at Diving Systems International.

The KMB-28B (Shown with optional KMB 18/28 head protector) is very similar to the KMB-18. Most parts on the KMB-18B are interchangable with KMB-28B.

The main difference between the 18 and 28 is the material of the mask frame itself. The KMB-18 has a hand laid fibreglass frame (yellow) while the KMB-28B frame is an extremely durable injection moulded plastic (black). The relative ease of production of the "28" frame accounts for the lower cost and quicker delivery of this mask. Other differences include: 1) The main exhaust body of the "28" is part of the frame itself and uses a #545-041 main exhaust cover 2) no comfort insert is required on the "28" 3) the main exhaust cover and face port differ from those on the "18"
