Run by a Boss. Not your boyfriend.
SISU isn’t just a mouthguard brand. We’re a woman-owned, women-led company redefining how athletes protect their game faces. Our founder didn’t wait for permission, she built a better mouthguard. And guess what? It wasn’t pink. It was powerful.
“You don't need to shrink it and pink it. You need to make it better.”
No Gag. No Bulk. No BS.
Our low-profile, custom-fit mouthguards let you breathe, talk, and hydrate—without pulling it out mid-game. Because who has time for drama or dental injuries?
- Super slim so you can trash talk clearly.
- Form-fit so you can breathe like a beast.
- No nonsense so you can focus on crushing it.
You bring the game. We've got your grill.
From D1 athletes to grassroots roller derby queens, women across every level of sport trust SISU to keep their smiles intact. You deserve gear that works as hard as you do—and doesn’t treat you like an afterthought.
