Portwest garment size guide & fit

Portwest garment size guide & fit

Choose your size using body measurements. These are manufacturer guide measurements, rather than the finished dimensions of an individual garment.

  1. Measure your chest or bust, waist and inside leg.
  2. Compare those measurements with the relevant chart below.
  3. Choose a size offered on the product, and check its fit and leg-length information.

Numeric waist sizes: where the product specifies a waist size in inches, choose that waist measurement. A waist size and an EU clothing label are different numbers.
