Scubapro Crystal VU Plus Dive Mask with Purge Valve

Scubapro builds this mask; FGSS carries it as one of our Amazon-affiliate picks. Low internal volume, double-sealed silicone skirt. 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 -- Scubapro'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.
