I bought this for my brother who has cancer and is very sensitive to the sun due to chemo. He explained that it really helps to protect yourself from the sun without getting too hot.
Pros
The MI Falcon Men's Long Sleeve T-Shirt is made with moisture-wicking fabric to help you stay dry and cool, even when you sweat.
Cons
The shirt is not suitable for colder temperatures and does not offer sufficient thermal insulation.
