I bought this for halloween 2009.  The black jump suite is fairly big.  You have to be 6' to really fit into it.  I am 5-6, and the suite fit ok, but was very loose even under the armour (another issue).  All the armour has strapps/velcro.  Is you are thin, the jump suite does not allow you to velcro the armour in the correct positions.  There should be multiple locations for velcro. The helmet does not fit snug.  You have to have a head the size of a watermellon.  It should come with addition foam inserts to allow for the perfect fit. The visor opening is so small, you have absolutely no vision to the left/right.
Worth $600?....not really.  Over all, glad I bought it...spent $600....wore it...and now it sits for history.
