I was in conversation with ETI last week about a separate topic and I thought I'd inquire about apparel. I was pleased ETI had some stock and is happy to ship. This is what was in stock as of last week. I scored 4 items!
Sorry for the tiny pics, images copied from a pdf to post here.
I was advised, "The T-shirt color (top right in image) is actually a lighter/mid color blue. The Escape Ball Cap (left in image) is blue in the front, white in the back."
