Give your young Notre Dame Fighting Irish fan gear that's strong enough to keep up with their seemingly never-ending energy. Give them this Under Armour Logo Lockup T-shirt. It's crafted with HeatGear technology, so they'll stay cool while they run around, and raglan sleeves which provide greater range of motion. Best of all, it features bold Notre Dame Fighting Irish graphics, so they can tout their fandom while they (hopefully) tire themselves out.
