If you want one of the UFC’ “Vegas Strong” T-shirts, you’re not alone.

On Sunday the Las Vegas community was stunned by a mass shooting that left 58 dead and approximately 500 injured when a shooter opened fire on a crowd at a Las Vegas strip outdoor concert.

On Friday the UFC, which is headquartered in Sin City, announced 100 percent of the profits from the sale of special shirts will go to “families of the victims and those affected by the shooting.”

As of Saturday morning, the shirts were mostly sold out in all of the popular sizes. (However, expect them to be restocked soon since sales will continue through the end of the month.)

Here are the various styles, available at ufcstore.com (and at other UFC retail locations):

UFC 216 takes place tonight at T-Mobile Arena in Las Vegas. The pay-per-view event, which features two title fights, has been a bit of a rallying point for the UFC and MMA fans. The organization has pledged to donate $1 million to the families affected by the shooting, and UFC President Dana White, who wore one of the shirts at UFC 216’s weigh-ins, said the organization will host 1,500 first responders at tonight’s event.
