    Great quality and customer service!

    I recently picked up this shirt after seeing my brother wear a different Bad Birdie shirt. He said he really liked the quality and fit compared to other gold shirts. I can attest they fit a lot better as they are not boxy and are cut more athletic - which is exactly what I wanted and needed.

    I ordered a L that was a little too tight (not massively) in the chest, so I exchanged for an XL and I love it. The customer support was great, no hassles and free return. Got the new shirt and wore it the next day!
