Measurements refer to body size, not garment dimensions, and are in inches, unless otherwise noted. Inseam measurements are from crotch to floor. Fit note: Patagonia's waders are less bulky than most brands yet still allow room for layering. The adjustable suspender and belt system can customise the fit +/- three inches in torso width and height.
Height: upto 5'9"
