This masks offers a large degree of coverage. The panaflex armor (foam) on the forehead and jawline help alot.
The panaflex armor and the visor must first be assembled. The strap has a tendency to loosen on it's own at the most inopportune times. My mask was an older version with the lens held in by tabs with o-rings on the end of them. These lenses are a pain to remove from and insert into the goggle frame. You pretty much have to pry them out with a screwdriver or other foreign object. When you do, you run the risk of scratching your lens. The mask is only moderately comfortable.
The Intruder offers good coverage and protection. However, the drawbacks of so-so fit, difficult lens change/clean, and the masks habit of coming loose make it difficult to recommend this mask. There are better masks for the same price.
The mask has never fogged on me. EVER. It provides good protection to the neck and forhead with the foamy add-ons. The lenses are durable.
The fit is a little tight. The visor is a thin plastic add-on that will break after a few good hits. My lenses are due for a replacement, but I've had them for about 3 1/2 years.
This mask has been suprisingly long lasting and very durable. I love the fact that they have never fogged on me. I wish they were a little wider inside, as they are a bit uncomfortable. Overall they have lasted longer than any other mask I've owned.
