I've used them as well. Essentially the same thing as the SmithOptics Boogie Regulator, except the Exoshield has no ventilation, so thus it fogs way more, making the Boogies better from the get go. I have even spoken with Revision regarding the Exoshield after I tried mine and they stated that they are not really meant for a soldier doing vigorous activity. They are more for vehicle drivers and support crew (air and ground) that have the need for NVG use. Its also a popular goggle set for parajumping. Edit: They are used in daytime as well with vehicle crews and are used by the conventional soldier/SF soldier, however are not a popular choice for high intensity activity for the reasons stated above.

In a nut shell they're a slightly less efficient version of the Boogie Regulators. Not worth the money IMO.
