I have ordered these several times and have only received genuine Hanes Nano shirts twice. Also the ones shipped and sold by Amazon are not real nano shirts. The ones received have zero 'nano' tags (real 'nano' shirts don't have a tag, which can clearly be seen in the photos. At least they have the correct collar/cuffs in most cases, but the sleeves are longer , the fabric is of lower quality). and the seams are rougher on the inside.
