Sport Tek Posi UV ® Pro Long Sleeve Tee ST420LS
The ST420LS is a long sleeve sun shirt with a soft, matte feel. The 4 oz polyester interlock has a UPF 50 rating, wicks moisture and uses PosiCharge so colors stay bright. It has set-in sleeves and a removable tag for comfort.
We recommend it for landscaping and ag crews, outdoor events, fishing and golf teams, and summer camps that spend long days in the sun.
