I actually bought this for myself to wear on morning dog walks in the hot southwest summer. I hate putting sunscreen on every day so I wanted something with long sleeves that would protect me from the sun while also being lightweight and breathable so I wouldn't overheat at 6:30 in the morning when it was already 100 F. I shopped Men's shirt because I wanted a looser fit and I liked the light color for visibility. I'm 5'9 size SM in women
