UNDERDOG MENTALITY – Heavyweight Vintage Grit Tee
- Vendor
- Next Wave Wear
Underdogs never give up — they go harder.
The UNDERDOG MENTALITY tee is built for those who’ve been overlooked, counted out, or doubted from day one — and kept pushing anyway. Featuring a bold, throwback-style bulldog QB and vintage athletic type, this design stands for grit, discipline, and a chip-on-the-shoulder mindset.
Made from 100% heavyweight cotton, this shirt delivers that old-school structure with modern comfort. Perfect for post-gym grind, team tunnel walks, or daily street-mode.
• Durable heavyweight cotton with a relaxed, structured fit
• Bold front graphic: “Underdog Mentality” + vintage football bulldog
• Natural distress-style print for that worn-in toughness
• Runs true to size, designed for everyday movement
💬 This isn’t a trend. It’s a mentality.
