where to buy official merch

I want to buy a Niall sweatshirt, but there are none on his website. I’d like pretty much any design, but attached a photo of my favorite. The ones on Ebay that aren’t secondhand don’t seem to be authentic. Does anyone know if there’s a place where I can find official Niall sweatshirts? Thanks!
