A great frame color. Looks black when wearing it but if you look through it it looks better. I had these in my oil drums, bought them just for this color. But it doesn't look good in anything else. In my opinion it doesn't look great on monster dogs. Wish they would use it more.

Olive is an interesting color, similar to Algae. Its translucent green hue looks good, but there are a limited number of lens options that go well with it.

This color is the main reason I picked up the Monster Dog in the Flouro Camo pack. I missed the color in the custom program, so I had no other recourse. I dig olive. I'm a military guy, so it pretty much goes with everything.

Great drab green color. Like other crystal frames, it can appear almost black under low light, but the color shines through when viewed under brighter conditions.

A fairly pleasant, mellow green that would go well with military camo but not much else.

As of this time they're only offered on the Warden frames. When they came out I was worried that they would be more of a lightish Army-type Olive Drab color, but Oakley's olive finish is more of a cross between Olive Drab and Gunmetal; not overly green but green enough to be noticed. Also, the finish of the metal is really nice; there's a slightly brushed metal quality to it, and with a slight metal sheen.
