The Profile Plus comes with an HD lens that blocks UV rays and reduces glare, which came in handy during our sunny day of shallow diving in crystal-clear viz. The mask features large seals that were very effective at keeping water out and, except in the case of some narrower faces, impressed testers with a comfortable, dry fit. The easily operated quick releases allow you to quickly and securely adjust the strap. The mask is more difficult to clear than its size would suggest, a trade-off for the deeper-set seals.
