The Zeal Optics Slate Goggle reminds us of the Smith IO but without the quick change tech. Its fun to look through and it’s got a good fit around the face. The Slate Goggle is not the same ultra fog proof goggle like Smith but it’s well built and has good colors to look through. The foam on the Zeal is better than Smiths tripple foam around the nose though. It’s got a wide viewing angle and its big on the face but not massive. We liked this goggle.
