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.
