While this isn't the worst, it certainly looks like amatuer hour. The NY looks washed out and bland, the two stripes on the sleeves don't go all the way around the sleeve, the numbers are slanted which is not needed, and the yolk being pointed is just silly. It's trying to be ultra modern for modernizations sake. The numbers being slanted to follow stripes seems to be a nod to the way the numbers wave to follow the wavy stripes on the Gorton's Fisherman jersey.
Icelanders stop making third/alternate jerseys; the Fishsticks jersey, the Orange Starburst jersey, the Black Baske-Hockey jersey, now this. The New York Islanders; making ugly third jerseys since 1996.
From what the Newsday article stated I believe that all the teams involved are going to release their Stadium Series jersey today and they will be available for purchase by the public on Black Friday.
