Men's 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.


El Cap Khaki
A secure, fast-drying 5-panel hat with a DWR (durable water repellent) finish, designed for performance in water and wind while offering coverage for the face, ears and eyes.
Forget the Internet—the best waves still go to people who are willing to set up camp and wait. A secure, fast-drying 5-panel hat designed for lightweight performance in water and wind, our Surf Duckbill Hat keeps the sun off when those first long interval lines start to show down south. Made of soft and durable 100% nylon with 50+ UPF sun protection and a DWR (durable water repellent) finish, it has a stiff foam brim that shields the eyes and holds its shape while still allowing clean duck dives. The dark underbill reduces glare from the water, and the COOLMAX® fabric headband wicks moisture and provides a comfortable fit. An adjustable chin strap keeps the hat in place in wind or bigger surf; it can be easily tucked away when not in use.
