I tested out the Lands End Sun.Life Polo on a recent visit to Maui. Coming from the cold in Salt Lake City, I was primed for a sun burn. I'm happy to say this shirt helped protect by back from the sun, and was a versatile lightweight travel shirt. I could wear it to the beach, take it off, put it back on, brush off the sand and go out for dinner.
I'm a size 46, so I picked the XL size which fit well. I washed the shirt at least 5 times, and found it held it's size and got much softer.
