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.

Frequently Asked Questions

1. What makes a t-shirt "FR" or flame resistant? 

An FR (flame resistant) t-shirt is made from fabric that won't continue burning once removed from a flame source, and won't melt onto skin like standard polyester can. Our crewneck t-shirts use 100% cotton that's inherently flame resistant, meaning the protection is built into the fiber itself rather than a coating that fades after repeated washing.

2. Are these crewneck t-shirts NFPA 2112 compliant? 

Yes, our FR crewneck t-shirts are designed to meet NFPA 2112 standards for flame resistant garments used in industrial settings where flash fire is a hazard. This makes them suitable for oil and gas, utilities, manufacturing, and other environments with FR dress code requirements.

3. Can I wear this shirt by itself or does it need to be layered? 

Both work. The 6.5oz cotton weight is substantial enough to wear on its own for most warm-weather and moderate-climate job sites. 

4. What colors are available in the FR crewneck t-shirt collection? 

This collection comes in black, sand, navy, indigo, grey, and burgundy, so you can match a required uniform color or choose a shade that hides dirt and wear on the job.

5. How should I wash my FR t-shirt to keep it flame resistant? 

Machine wash in cold or warm water and avoid fabric softener or bleach, both of which can break down the fibers that give the fabric its flame resistant properties over time. Tumble dry on low and avoid ironing directly over any printed logos or tags.

6. Do you offer free shipping on FR crewneck t-shirts? 

Yes, any order over $99 ships free within the US. You can mix and match items across our FR Shirts and other collections to reach the free shipping threshold.

7. What's the difference between this collection and your Lightweight Crew Neck T-Shirts? 

This collection uses a heavier 6.5oz cotton fabric suited for year-round wear and added durability. Our FR Lightweight Crew Neck T-Shirts use a lighter fabric built specifically for hot weather and summer shifts.
