There's still no firm date for when the Seattle Sounders will release their 2016 kits, but they've at least released a teaser photo that provides some clues as to what it will look like.
The most obvious element in this black-and-white photo is the tag "Sea of Green / Sky of Blue." While it's a bit obvious that one of these shirts is going to be green -- yes, the Sounders will have new primary shirts despite the current ones only be a year old -- this appears to be further evidence that there will a blue third jersey.
