The band were eating dinner after a show with I Prevail in San Antonio, Texas when thieves broke into their van and stole "many personal belongings".
"Nights like tonight are hard," wrote vocalist Mikey Carvajal.
"However, you can't steal my punk rock heart, suckas."
They also shared a statement via Facebook, including a link to their Paypal for anyone who wants to help out with a donation.
"See these birds? They are eating random pieces of popcorn outside of Target right now. They are taken care of. They find strings and sticks and paper to build their homes. And that's what we do. God provides strings and sticks and random things for us. All we have to do is be grateful for them."
"This is what it's like being in a band. Our personal belongings (passports, laptops, iPads, money, in ear monitors, video game systems, medications, external hard drives, etc...) and some of our gear was stolen last night. But you can't steal the heartbeat of a punk."
"People that do hurtful things are people that are hurting. If you have ever been forgiven for something, then you know how amazing it feels to be forgiven."
"We choose forgiveness today, and we choose to love today. Pray for those that are hurting and feel the need to do hurtful things, family. Choose love and keep that P.M.A.!"
"Here is the official link to our PayPal if you would like to help. We love you."
A number of bands have also been robbed on the road recently, including Fit For A King and The Browning.
