Mat Side Coaching Staff Tee
Unofficial opinions provided before, during, and after every match.
No clipboard. No whistle. No official role — but everybody knows who to look at when things go sideways on the mat. The Mat Side Coaching Staff Tee is for the jiu jitsu dad who has never once held back an opinion and doesn't plan to start now.
Bold on the back. Clean on the front. Built to last.
THE DETAILS
100% combed ring-spun cotton
5.5 oz/yd² heavyweight fabric — substantial feel, not flimsy
Drop shoulder sleeves for a relaxed, modern fit
Side-seamed construction for a clean, structured silhouette
Reinforced 1×1 ribbed collar that holds its shape
Tear-away tag for all-day comfort
Front print + back print
Available in Black, Navy Blazer, and Vintage Black
Sizes S–3XL
WHY YOU'LL LOVE IT
This is the tee that says everything your dad has been saying from the sidelines for years — just in a much cleaner font. Heavyweight cotton that softens with every wash without losing its shape, and a smooth surface that keeps the graphic sharp and readable from across the gym.
Wear it to tournaments, the academy, or anywhere you want people to know exactly where you stand.
The perfect gift for the jiu jitsu dad, coach, or that one training partner who always has something to say.
Fits true to size. Size up for a looser, more relaxed fit.
This product is made especially for you as soon as you place an order, which is why it takes us a bit longer to deliver it to you. Making products on demand instead of in bulk helps reduce overproduction, so thank you for making thoughtful purchasing decisions!
