Pick a size from the garment, not the guess
Our chart lists the shirt, not your body. A tape measure and a tee you already like will get you closer than a letter.

Letter sizes move. A medium from one brand can be a large from another. The Northline chart is a garment chart: chest width, body length, and sleeve, measured on the shirt in inches.
Lay a tee that fits the way you want on a flat table. Button nothing. Measure across the chest, pit to pit. That number is the chest on our chart. If you are between two sizes, the classic tees can go either way. For hoodies, size up if you want a layer underneath.
Hats are different. Measure around your head just above the ears. S/M covers 21.25 to 22.5 inches. L/XL covers 22.75 to 24 inches. Between those ranges, take the larger cap. The clasp can tighten. It cannot add room.
The photos are not a fit model for every body. Use them for color and silhouette. Use the chart for the order.
