The Hollis M4 Frameless Low Volume Scuba Diving Mask features a frameless silicone skirt and a low-profile design that fits a wide range of faces while delivering superior peripheral and vertical vision. The low-volume silhouette reduces internal air space for easier equalization and a closer, more natural mask feel during dives.

The single-lens configuration and silicone construction offer durable performance for regular scuba and diving use, with a design that pairs well with standard gear setups and remains comfortable under a wetsuit or drysuit collar.
