You know how saints would do weird things like wear itchy hair shirts because suffering on purpose made them cool or something? It stands to reason, then, that things like soft fabrics are part of Hell's temptations, so we went all-out creating a blanket that has appropriately demonic imagery and is softer than Satan's pajamas. The front is adorned with our badass Heresy artwork of a demon presiding over an infernal gathering of ghostly skulls as they plan to overthrow uncomfy and itchy blankets, while the back is black plush fleece. If being comfy and cozy is considered heretical, it might be time to throw the whole belief system away.
Note that due to the method of printing part of the white blanket can be seen through the black printed back - I thought it looked kinda neat actually. But that's a thing.
