Simple Tee
For the ones who weren’t handed the blueprint — they wrote their own. The Simple Tee reps the Underdog Playbook mindset: overlooked, underestimated, but never outworked.
This premium, ultra-soft shirt features a bold, minimalist design with our iconic underdog symbol and gritty football play elements that remind you to keep pushing forward, brick by brick. It’s a daily uniform for the grinders, the dreamers, and the ones who know the standard beats success every time.
Wear it. Live it. Stay Underdog.
