When protecting themselves bears make themselves look bigger by fluffing up their fur and standing on their hind legs. When angry they will growl, pound their paws on the ground and charge towards whatever is bothering them. You can do that too, OR you can grab a Bears Face Mask! Official custom-made North Sydney Bears Face Masks are now available. 3-ply, locally made masks – protect yourself and show your colours, Red & Black Forever! Available in 3 sizes: Youth, Adult & XL.
