I'm 6'1", about 13 stones and athletic in build (wide shoulders, slim waist).

I really liked the Uniqlo Supima T-shirts, they fit so well! But now they no longer do them. Boo!

Can anyone recommend a brand that would fit similarly? I take a Large in the Uniqlo T's, if that helps. Looking for quality as well as fit, am prepared to spend a bit.
