The hood on the Iron banner cloak clips through both Trials helmets (extremely noticeable) as well as the raid helmet (less noticeable, same area). This is easy enough to see if you equip the IB cloak and either trials helmet. While looking at the character from the front you can see it on the top right (your right, character's left) of the hood. It would be nice if this could be patched so we could wear these cloak / helmet combinations without looking ridiculous.
