How to Measure:

  • Chest Width: Measure across the chest, from armpit to armpit, with the shirt laid flat.

  • Length: Measure from the highest point of the shoulder down to the bottom hem.

  • Sleeve Length: Measure from the center of the back (at the base of the neck) to the sleeve hem.

Fit & Fabric:

  • Fit: Retail fit (slightly slimmer than classic boxy t-shirts)

  • Material: 100% ring-spun cotton (some colors may have slight polyester blends)

  • Pre-shrunk: Yes, but minimal shrinkage may occur after washing

If you're between sizes or prefer a looser fit, we recommend sizing up!
