JBrown is urethane. Roids mask is latex. And it's pretty durable and is comfortable and gives it that sturdy look. Wouldn't know how it compares to a urethane mask as I've never owned one but I really like it and it feels durable and isn't flimsy by any means.
Ohkay well thats good then! I think I saw some pictures of JBrowns mask and it didnt look like it was holding its shape very well, but it just must have been the way it was sitting when they took the photo
