Stanfield's Men's Underwear Sizing Guide

Use this guide to find your best fit for Stanfield's Men's Underwear style.

Experience the legendary durability of "The Underwear That Won the West"—and the North—with Stanfield’s at Wei’s Western Wear. Stanfield’s sizing philosophy is rooted in "Generational Reliability," providing a consistent, traditional fit that has remained a staple for Canadian tradesmen and outdoorsmen for over 160 years. Whether you are stocking up on the Stanfield's Men's Premium Brief - Three Pack or seeking the flexible support of the Stanfield's Men's Premium Boxer Brief - Two Pack, you are choosing garments crafted with premium long-staple cotton. This dedication to high-quality natural fibers ensures a breathable, moisture-wicking foundation that maintains its structural integrity and shape, wash after wash.

A unique fit characteristic of Stanfield’s is the signature "Plush Back" waistband, designed to sit securely without rolling or digging into the skin. A common sizing concern for Wei’s customers is the "shrinkage factor" associated with 100% cotton; however, Stanfield's utilizes a specialized knit that accounts for standard laundering. Generally, Stanfield's underwear runs true to your natural waist size. For top-sellers like the Premium Brief, the paneled front and fly pouch provide a contoured, supportive fit that isn't overly restrictive. If you are between sizes or prefer a looser, "old-school" feel, we recommend sizing up to the next whole size. By following our guide, you'll achieve a "Wei's approved" fit that stays "cool, calm, and collected" from the first hour of your shift to the last.
