    Sizing Notes

    Measurements are stated in inches unless otherwise indicated.

    SHORT: Some pants are available in short sizes, which generally means an inseam that is 2.5 inches shorter than regular sizes.

    TALL: Some pants, shirts, jackets and parkas are available in tall sizes, which generally means an inseam that is 3 inches longer and a rise that is 1 inch longer, a shirt or jacket body that is 2 inches longer, a parka body that is 2.5 inches longer and sleeves that are 2.5 inches longer than regular sizes.

    Capri or cropped pants have an intentionally shorter inseam—reference the technical specs instead of this chart.
