Sport Tek Youth Posi UV ® Pro Tee YST420
The YST420 is a kids' tee with built-in sun protection. The 4 oz polyester interlock has a UPF 50 rating, a soft matte feel, moisture wicking and PosiCharge color lock so camp colors stay bright all summer. It has set-in sleeves and a removable tag.
We recommend it for summer camps, swim and dive teams, youth baseball and softball, and school field days.
