Little man loves to get "Owsigh", so I figured he needed some duds to show that off. My Patagonia gear has been stellar... and the little dude deserves no less. He's 19 months and I got him the 2T and it fits really well, pretty much like all other 2T stuff we've bought him. So I'd venture to say size is pretty true. Totally top notch, super soft and comfy fabric. Everything's come out in the wash so far also. Little man seems quite pleased so, so am I.Will buy another when he out grows it, and I would recommend to a friend.Oh yeah and a surfer ant with a leaf... how stinkin' pimp is that.
