HELP! Need Lego Jacket/Coat

I'm trying to find a new or used Lego Jacket for my brother.  He currently
wears one from Legoland that is blue with a sweatshirt lining inside.  Not so
fussy on style or color.  I'm just running into deadends trying to find a
jacket of any kind.  Can Legoland park merchandise be found online anywhere?  

Thanks
