The first tee built around your neck. Our collar technology eliminates wrinkle and sizes precisely to your neck measurement — so it looks sharp every time.
Three layers. Zero wrinkle. A precision inner band that sizes to your neck and holds its shape through everything.
Outer Shell
320gsm heavyweight cotton. Pre-shrunk, garment-dyed. Retains shape wash after wash.
Structured Band
The core innovation. A rigid-yet-flexible inner ring calibrated to your neck circumference — no wire, no fusing.
Inner Lining
Soft cotton jersey sits against the skin. Moisture-wicking, tagless, seamless comfort all day.
Zero Wrinkle
The structured band prevents the collar from folding, curling, or creasing — ever.
Neck Calibrated
Sized by circumference, not chest. Three fits: Contour, Balance, and Ease — matched to your neck measurement.
50+ Wash Tested
Engineered to outlast regular wear. Collar integrity verified through 50 wash cycles with no degradation.

Our Story
"A great tee starts and ends at the collar."

Size Guide
Every CollarCore fit is engineered to your neck — not just your chest.
How It Works
FIND YOUR COLLAR FIT
Traditional t-shirt sizing ignores the most important part — the collar. CollarCore tees are sized by neck circumference, so your collar sits flush, stays flat, and never wrinkles.
To find your size, measure around the base of your neck where a dress shirt collar would sit. Keep the tape snug but not tight.
