OTS Guardian Full Face Dive Mask with Communications

Removable 2nd stage for cleaning/storage -- that's the core of what OTS built here. One-piece silicone skirt, double face seal. A softer skirt against a stiffer frame is usually what separates a mask that seals reliably from one you're constantly readjusting. As with most gear like this, sizing runs by brand -- OTS's chart is the more reliable reference than the label alone. FGSS doesn't stock this one ourselves -- it's an Amazon-fulfilled listing, and as an Amazon Associate we earn a small commission if you buy through it, at no extra cost to you.
