I'm so glad my husband is mowing the lawn or working in the garden in this SPF 50 Long Sleeve T-Shirt. Made from polyester, it's lightweight and highly breathable, so protective long sleeves won't be an issue in hot weather. It's nice to know it's protected from the sun's harmful rays. The shirt is beautiful, well made, easy to wash and dry. It's soft and smooth and my husband loves it. I think it will get a lot of use.
