Lessons Learned: The correct sizing ALL depends on the "fit"!

I love UA products, and I've purchased MANY UA shirts of various "fits". But I've returned/exchanged half of them to ultimately result in attaining the correct size. I've learned the following VALUABLE lesson: I'm size SMALL if the fit is "Loose". (Med is too baggy.) I'm size MEDIUM if the fit is "Fitted". (My favorite combination.) I'm size LARGE if the fit is "Compression". (Med is comically tight.) I realize not everyone has the same build as I do. (FYI, I'm 5'7", with a 41" chest, 29" waist, and a flat gut.) BUT in general, I suggest using my experience as your guide to save you the headache of returns/exchanges.

Great top true to size. Can’t fault the quality of this product.

Good quality product, true to size. Looks sharp on and warm. Highly recommend
