Description

Not perfect. Not finished. Just forward.

A bold circular emblem — arrows, gridlines, and the phrase Progress over Zero / Keep it Positive — reads like a mission patch for the kind of person who measures success in momentum, not milestones. The crisp orange-and-white print pops against a dark background without shouting. It’s the shirt for the math teacher who sneaks a growth mindset lesson into every unit, the coach who tracks small wins, and anyone who knows that greater than zero is still greater than zero.

Wear it to the classroom. Wear it to the gym. Wear it anywhere you want your mindset visible but understated — the kind of shirt that starts a conversation with exactly the right people.

🍎 The Tee That Earns Its Keep.

Made on the Gildan Softstyle 64000 — because you deserve something that doesn’t feel like a paper bag by third period.

  • 4.5 oz. 100% ring-spun cotton — soft straight out of the package, no break-in period required
  • DTG printed — the design goes into the fabric, not on top of it. No cracking. No peeling. No drama.
  • Tubular knit, no side seams — clean silhouette, all-day comfort
  • Runs true to size. Unisex fit. Sizes S–3XL.
  • Available in Dark Chocolate, Navy, Black, Military Green, Heather Navy, and Sapphire.
  • Printed and shipped in the USA.

The perfect gift for math teachers, coaches, and anyone who lives by the greater-than sign — or an extremely justified treat for yourself. Progress > 0. Always.

Premium Classroom Comfort

Made from 100% ring spun cotton — softer, stronger, and more durable than standard cotton, because you've got enough things falling apart on a Monday.

Pre-shrunk so it fits the same way on day one as it does after your 47th wash. At 4.5 oz, the fabric is lightweight and breathable enough to keep you comfortable from first period to last.

And the relaxed unisex fit? True to size and flattering on every body — no guessing, no surprises, just a shirt that works as hard as you do minus the drama. Cause you deal with enough of that.

Built to Last thru Friday

Built to last through every school year, every wash, and every "why is there glitter on this again" moment. Double-needle stitching at the shoulder, armhole, neck, waistband, and sleeves means this tee holds up to repeated wear without falling apart — unlike your patience on a Friday afternoon.

The quarter-turned seamless collar keeps its shape over time and stays crease-free, so it looks as good on week fifty as it did on day one.

And the tear-away label means no scratchy tag digging into your neck during a six-hour school day. You're welcome.

Free & Easy Returns

Love your tee or your money back. Simple as that. No essays, no rubrics, no partial credit — just a full refund within 30 days if it's not for you.

Every USA order is also printed and shipped right here in the States, because we're as American as a school bake sale and proud of it.

Comfortable Enough to Forget You're at Work

Our T-Shirts are made by Educators for Educators. So you can believe that they will be soft enough to survive a staff meeting. Sturdy enough to outlast the school year. Our tees are built for the person who gives everything from bell to bell — and still has opinions about the copy machine in the staff lounge that is too far away, always has a line, and is almost always jammed.

Wear what you love. Especially when what you love is making it very clear how you feel about Mondays.
