Vipers and the other gangs commonly have them
care to share your secret on how to get the hat off?
I have seen this trick mentioned different places. Here is one description of the process.
"This is strange but it works 100 percent with Cass and Veronica. Get a Legion recruit Helmet, Ballcap and glasses(the ones that are together) and then sunglasses.
Put the legion recruit helmet and ballcap w/glasses in their inventory, then back out until they are wearing the recruit helmet. Then go back itno their inventory and take out the recruit helmet and slip in the sunglasses. Exit.
They will now be hatless with sunglasses. IMHO, they both look so completely better. I do this everytime. Sometimes when you zone you have to re-put the recruit helmet, but its like once or twice every few hours. Its worth it."
