Ariat Men’s Tops and Jackets are designed to deliver a true-to-size, performance-ready fit that blends comfort and durability. Ariat uses men’s sizing standards with room where it matters most — through the chest, shoulders, and arms — so you can move freely on the job site or out on the trail. Most customers can confidently choose their regular size, but if you plan to layer with hoodies or flannels, sizing up one size can provide extra room without altering the overall fit.

Work-focused styles like the Work Shirt Flame Resistant Lightweight Henley and the Flame Resistant Bighorn Plaid Long Sleeve Shirt offer a slightly structured fit that sits close to the body without feeling restrictive. The Flame Resistant Ripstop Softshell Shirt Jacket is designed with extra room for layering, making it ideal for cooler conditions. For casual wear, the Big Bull Rider T-Shirt delivers a relaxed, easy fit that works well on its own or under outer layers.

To ensure the best fit, measure your chest and arm length, then compare those numbers to Ariat’s size chart. Matching accurate measurements to your chosen size helps guarantee all-day comfort, range of motion, and lasting wear, whether you’re working outdoors, riding, or keeping it casual. Accurate sizing means your Ariat men’s tops and jackets feel as good as they perform.
