Crewneck T-Shirts

FR Crewneck T-Shirts Built for the Job Site 

When you're working near heat, sparks, or open flame, a regular t-shirt isn't just the wrong choice — it's a dangerous one. Our FR crewneck t-shirts are built specifically for workers who need flame resistant protection without giving up the comfort of a classic, everyday tee. Each shirt is made from heavyweight 6.5oz 100% cotton, designed to meet the demands of oilfield, electrical, welding, and industrial job sites where standard cotton or polyester shirts would melt, drip, or ignite.

Unlike bulky FR outerwear, this crewneck collection gives you a long sleeve flame resistant t-shirt you can wear on its own in moderate weather or layer underneath a jacket, hoodie, or coverall when temperatures drop. The crew neck cut keeps things simple — no buttons, no zippers, just a clean fit that works under PPE without bunching or chafing.

Why workers choose our FR crewneck t-shirts:

Every shirt in this collection is flame resistant by design, not by an added chemical treatment that washes out over time. The 100% cotton construction stays breathable through long shifts, which matters when you're wearing FR gear for 8, 10, or 12 hours straight. We offer this crewneck tee in six colorways — black, sand, navy, indigo, grey, and burgundy — so crews can match company colors or simply pick what holds up best against dirt and grease on site.

These shirts work well on their own for warehouse, refinery, and field work, but they also pair naturally with the rest of our FR lineup. If you need something even lighter for summer heat, check out our FR Lightweight Crew Neck T-Shirts. 

Looking for a different neckline? 

Our FR Henley T-Shirts offer a similar long sleeve fit with a button placket. If you're building out a full FR wardrobe.

All of our flame resistant crewneck shirts are part of our broader FR Shirts collection, where you'll find every style we carry — snap front, button down, henley, and more — all built to keep you protected without weighing you down. Every order over $99 ships free, and if you have questions about sizing, certifications, or care instructions, our team is just a message away on the Contact Us page.

If you're outfitting more than just your top half, take a look at our full FR Clothing range, which covers everything from shirts and pants to outerwear in one place. Need something heavier for the colder months? Our FR Jackets for Men and FR Hoodies for Men are built to layer right over this crewneck tee. And if a button-front or snap-front style fits your job better than a pullover, our full FR Shirts for Men collection has you covered.
