Please be sure to read the profile! These arm covers are perfect for sun protection and gardening! They are made with polyester lace fabric and 100% cotton double gauze and cotton fabric for the white parts. They are breathable and have elastic at the arm and wrist to prevent slipping. You can replace the elastic yourself if it's too tight or too loose!
