I read in a couple of the reviews below that the tube was too coiled in the package.  This is true.  However,
I was able to straighten it out pretty well by running sections of it under my hottest tap water and pulling it straight while the tube cooled.  After my son wore it for halloween, I have to change my review to only 1 star.  It was very uncomfortable for my son to wear.  He said it was itchy.  The ears & crown kept flopping forward and unless you walk around with your arms stuck out straight, it just looks pathetic.  I felt bad for him.  We almost went home and changed him into last year's Spiderman costume.
