Great fitting comfortable low volume streamlined mask
The IST M-99 ideal mask for free diving because the mask is compact, agile, and super low volume.
Plastic and silicone integrated injection method molds SEAL’s soft, hypoallergenic silicone skirt directly onto the frame. This technique requires fewer parts in the mask’s construction, resulting in a lighter and more comfortable mask that creates less drag in the water.
Lenses brought as close to the eyes as possible for a better field of view. This design is appreciated by underwater hunters seeking prey, as well as by scuba divers and skin divers looking for a comfortable, low-volume mask that offers the best view of underwater wonders.
Easy-adjust buckles swivel for a perfect, custom fit with the diver’s preferred strap location
