Sweatshirts

FR Sweatshirts Built for Cold-Weather Job Sites 

When it gets cold on site, you need something that actually holds up — not a regular cotton sweatshirt that bunches under gear and gives you zero protection if something goes wrong. Our FR sweatshirts are built from heavyweight 12oz 100% cotton in a pullover cut, giving you serious warmth without trading away the flame resistant protection your job requires. No hood, no zip — just a solid, straightforward pullover that layers cleanly under a jacket or wears well on its own on a cool day.

The 12oz cotton build is noticeably heavier than most FR shirts and lighter hoodies in our lineup. That's the point — this is the piece you reach for when it's genuinely cold out and you need something with real insulating weight, not just an extra layer.

Why workers pick this over a lighter FR hoodie:

A lot of guys have a lightweight FR hoodie for mild days and want something heavier once temperatures actually drop. That's exactly what these FR sweatshirts cover. The 12oz cotton holds heat better than a 6oz or 8oz fabric, and the pullover cut keeps the wind out without the bulk of an FR jacket. It sits cleanly over most FR shirts — snap shirts, crewnecks, henleys — and sits just as cleanly under an FR jacket when it gets cold enough to need both.

Available in black, navy, charcoal grey, and OD green. Practical colors that work for most uniform requirements and hold up well against the kind of dirt and grease that come with industrial work.

If you're after something with a hood instead of a plain crew neck, our FR Hoodies for Men collection covers hooded options at different weights. For heavy-duty cold-weather outerwear on top of this sweatshirt, our FR Jackets for Men are built to layer over it. And if you want to see the full picture of what we carry across shirts, pants, and outerwear, the FR Clothing collection has everything in one place.

Frequently Asked Questions

1. What's the difference between an FR sweatshirt and an FR hoodie? 

The main difference is the neckline — an FR sweatshirt has a plain crew neck, while an FR hoodie has an attached hood. Both offer flame resistant protection, but if you want extra coverage for your head and neck on cold or windy days, a hoodie does that. If you prefer a cleaner, simpler pullover without the hood, the sweatshirt is the better pick. Our FR Hoodies for Men collection covers the hooded options.

2. How heavy is the fabric on these FR sweatshirts? 

12oz, 100% cotton. That's on the heavier end for FR tops — noticeably thicker and warmer than the lighter shirts and hoodies in our lineup, which makes it a better fit for cold weather than mild-weather layering.

3. Can I wear this FR sweatshirt under a jacket? 

Yes, the pullover cut is specifically good for layering under an FR jacket. No bulky hood or zip to create friction, just a clean layer of warmth between your FR shirt and outer jacket. Our FR Jackets for Men pair well with it.

4. What colors are available in the FR sweatshirt collection? 

Black, navy, charcoal grey, and OD green.

5. Is the 100% cotton construction genuinely flame resistant — not just treated? 

Yes. The FR protection comes from the cotton construction itself, not a surface treatment that degrades with washing. Standard care applies — cold or warm machine wash, no bleach or fabric softener, tumble dry low.

6. What's the difference between this collection and your FR full zip hoodies? 

This is a pullover with a crew neck — no zip, no hood. The full zip hoodies have a front zipper and hood, which makes them easier to put on and take off and gives you more ventilation control. Which one works better depends on your preference and how much adjustability you want on the job.

7. Where can I see your full range of FR outerwear? 

Our FR Clothing collection has everything — sweatshirts, hoodies, jackets, and the rest of our FR lineup — in one place.
