Official measurement standards

Garment Size Charts

Compare these garment measurements with a similar item you own, then confirm the selected product’s current size and color availability.

How to measure

  1. Chest width: Lay a well-fitting garment flat and measure straight across about 1 inch below the armpit seam.
  2. Body length: Measure from the highest shoulder point to the bottom hem.
  3. Sleeve: Follow the column label—tee sleeves are measured from the shoulder; fleece uses center-back sleeve length.

Measurements are in inches and manufacturer tolerances can apply. The product page’s live variant selector is the authority for sizes currently sold.
