Fit Guide

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.

How to Measure for Tops and Bottoms

1. Measure your arm length

With elbow bent, measure from the center (back) of neck to elbow and down to wrist.

2. Measure your chest

Relax your arms, then measure around the fullest part of your chest/bust.

3. Measure your waist

Bend slightly to one side to find your natural waist. (This will be the crease created from bending). Then, stand erect and measure around your body at the crease points.

4. Measure your hips

Stand relaxed with feet shoulder-width apart. Now, measure around the fullest part of your hips and seat.
