Welcome to Underdog

This brand exists because we've been and still are, the underdog. Not in fighting, but life itself. When no one believes in you and you're faced with hard shit, you have two options: fold or figure it out. That mentality doesn't stop at the gym.

Being the underdog makes you hungry. You go and get shit because you have to. Any obstacles, you find a way around it. So this brand was built to serve as a reminder to go out and get it, and know that there's others doing it with you.

Lightweight and breathable. Waistband is also flattering and fairly firm - you could probably size up for a looser fit and still tighten the waistband

BJJ shorts are the right length for rolling, love the stretch and drawstrings can be done up tight which is good. Also rashy feels nice and thick/ buttery.
