The Tee That Looks Sharp Without the Button-Up
You know the gap between a plain crew tee and a full button-up.
One feels too casual. The other feels like too much for a Tuesday.
This one sits right in the middle — easy to throw on, but it actually looks like you put thought into it.
That's the notched stand collar doing the work. It stands up just enough to frame your neck, with a clean open split at the front that gives the shirt real structure. Pair it with the slim cut and a basic tee suddenly reads a lot more intentional. Smooth, stretchy, breathable — comfortable from the first wear.
One of Our Fastest-Moving Men's Styles This Season
✓ A COLLAR THAT LOOKS PUT-TOGETHER WITHOUT TRYING. The notched stand collar sits up softly with a small open split at the throat. Sharper than a crew neck, easier than a button-up — the kind of detail people notice without knowing why.
✓ A FIT THAT FOLLOWS YOUR FRAME. Cut close through the chest, shoulders, and arms for a clean athletic line, with enough stretch to move freely. It reads tailored without feeling like a compression layer.
✓ BREATHABLE FABRIC THAT KEEPS UP. A smooth performance knit that moves air and wicks sweat, so it stays comfortable from a midday coffee run to a warm room later that night.
✓ EIGHT COLORS, M THROUGH 5XL. Everyday Black and Navy, clean White and Gray, plus a few that stand out — built across a real size range, not just the standard three.

Your Questions, Answered
How do I pick my size?
This one's cut slim and runs a little snug, so we recommend going one size up from your usual US size — especially if you're between sizes or carry muscle through the chest and shoulders. Sizing up gives you the cleanest, most comfortable fit.
Is the fit really that slim?
Yes — it's tailored close through the chest, shoulders, and arms for that athletic look. There's stretch built in so it moves with you, but if you'd rather a more relaxed drape, size up one or two.
Is the fabric thin or see-through?
It's a smooth mid-weight performance knit — light enough to stay cool, but not see-through. Black and Navy are the most opaque; the lighter shades read a touch lighter in bright sun.
What does the collar look like when it's on?
The stand collar sits up softly around the neck with a small open notch at the center. It frames your face and adds structure without feeling stiff or formal — sharper than a crew, easier than a button-up.
Will the colors match the photos?
Close, yes. Screens vary slightly, but each shade is shown as true as we can get it — Black is a true black, Navy runs deep, and the lighter tones stay soft and clean.
