CM = Centimeters IN = Inches
Measurements refer to body size, not garment dimensions, and are in inches, unless otherwise noted.
* Inseam will vary depending on style; when lengths are offered, "short" is 30, "regular" is 32 and "long" is 34, unless otherwise noted.

Though each Patagonia® product is designed and shaped specifically for its intended use, we can generalize our fit descriptions in four ways:

Formfitting

Conforms to the body's contours.

Slim Fit

Closer-fitting. Slim-fitting technical garments may be worn over baselayers and light midlayers.

Regular Fit

Neither slim nor oversized. Regular-fitting technical garments may be worn over heavier midlayers.

Relaxed Fit

Drapes loosely on the body.
