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.
Neither slim nor oversized. Regular-fitting technical garments may be
worn over heavier midlayers. Men’s regular fit pants have a slimmer fit
through that thigh, lower leg, and cuff.
Relaxed Fit: Drapes loosely on the body. Men’s relaxed fit pants have a bit of extra room through the hip, thigh, lower, and cuff.
