IFR Unisex Workwear Sizing Guide

Use this guide to find your best fit for IFR unisex workwear.

Prioritize your protection on the job with the industrial-grade reliability of IFR Workwear at Wei’s Western Wear. IFR’s sizing philosophy is rooted in "Functional Safety," ensuring that flame-resistant (FR) apparel provides a loose, comfortable fit that allows for essential air insulation between the fabric and the skin. This "buffer zone" is critical for thermal protection. Whether you are outfitting yourself in the IFR UltraSoft® Deluxe Coveralls or the high-visibility IFR 7oz Deluxe Striped Work Shirt, our unisex collection is engineered to meet stringent CSA and NFPA standards while providing the mobility required for demanding environments like oil and gas, mining, and electrical sectors.

A unique fit characteristic of IFR Workwear is the "Suit-All" design, which uses a versatile block to accommodate both men and women comfortably. A common sizing concern for Wei’s customers is the "Tall vs. Regular" dilemma; because mobility is key, IFR offers extended lengths in most top-selling products. For example, the IFR UltraSoft® Duck Bib Pants feature adjustable straps and a generous cut through the waist to allow for layering over winter base layers. We generally recommend that men who are 6'0" or taller opt for Tall sizes to ensure the sleeves and hems provide full coverage during movement. For women, the unisex fit typically translates to sizing down one full size from your standard North American women's size. By following our IFR size chart, you’ll secure a professional, safe fit that stands up to the toughest Canadian workdays.
