I think I'd reword this...

For some reason, grammar and spelling errors really jump out at me when part of something designed for public consumption (e.g. books, magazines, advertising, menus). This isn't really that kind of error, and may even be accurate, but I still think I'd find a different way to say it. From the Mirage website:

Quote

In freefall loose flaps are sloppy, distracting and potentially downright dangerous. Mirage containers are well known for staying closed until YOU want them open. In fact, our main pin protection is so tight that the main pin cover doesn’t even come open on deployment. We have zero bridle exposure, and our riser cover security sets the industry standard for reliability.

Wouldn't most skydivers consider the bolded part a bad thing?

Sounds correct. I jump a Wings container, and my main pin cover never comes open on deployment, and is still closed after I land. The same design is used on Mirage containers. The bridle comes from the right, then the pin goes into the closing loop and the other side of the bridle comes out from the right side as well. So on deployment there is no reason the flap should come open.
But i see your point. Maybe I'd get rid of the "main pin protection is so tight" claim, because the tightness has nothing to do with it, it has more to do with the actual design of the flap.

I think I'm going to join the questioning hordes here, why shouldn't the pin cover remain closed during the opening sequence?

Do you want to have an ideagasm?

Because of the preceding sentence, it sort of implies that their container won't come open even when you want it to.

Of course, that's incorrect. But the wording could be misleading for someone who doesn't have a prior understanding of the design.

I suggest that it would be better with something like:

"Mirage containers are well known for staying closed until YOU want them open. In fact, our main pin protection is designed so well that the main pin cover stays closed even when the container opens for deployment."
