ActionWear Workwear Sizing Guide

Use this guide to find your best fit for ActionWear.

When your safety depends on your gear, the ActionWear Flame Resistant collection at Wei’s Western Wear provides a sizing philosophy built for the most demanding industrial environments. ActionWear specializes in high-performance Nomex® IIIA fabrics, designed with a "safety-first" fit that balances protective coverage with operational comfort. Unlike standard workwear, FR garments like the ActionWear Hoodie Pullover FR and the ActionWear Jacket Flame Resistant Hi-Vis are engineered to be unlined and lightweight (7.5 oz), ensuring that the fabric sits close enough to the body to prevent snagging while allowing for the essential air gap required for thermal insulation.

A common sizing concern with Nomex gear is its inherent lack of stretch compared to treated cotton blends. To address this, the ActionWear Flame Resistant Nomex Bib Overall and the ActionWear Men's Vest FR CAT 4 feature generous armholes and elasticized gussets to maintain a full range of motion. Because these items are often worn over base layers, top-selling pieces like the ActionWear Sweater Flame Resistant Zipper are cut with a slightly relaxed torso. For most users, we recommend staying true to your measured chest size; however, if you are layering the CAT 4 insulated vest over a heavy parka, sizing up by one ensures the reflective strips and CAT ratings remain effective without restricting your movement on the job site.
