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.


Measurements refer to body size, not garment dimensions.

We apply wicking chemistry to our active styles to allow sweat and moisture to rapidly move from the skin to the surface of the garment, where it can evaporate into the air.
