FR Bottom Wear

FR Bottom Wear — Flame Resistant Denim Jeans & FR Pants

Your legs are just as exposed as the rest of you on a hazardous job site, and a regular pair of jeans won't cut it when there's flash fire or arc flash in the picture. NKE's FR bottom wear covers every style of lower body protection — from stretch denim jeans to heavy-duty canvas work pants — all built from flame-resistant cotton that won't keep burning once the ignition source is gone.

FR Denim Jeans for Every Cut and Job

Not every worker wants the same fit. That's why NKE carries multiple FR denim styles in this collection. The FR Stretch Basic and FR Stretch Fashion Jeans are both 10.5 oz, 98% cotton / 2% spandex — same FR fabric, different cuts. The Basic is a clean, no-fuss fit for everyday wear. The Fashion cut runs slimmer for guys who want something that doesn't look like a uniform. The FR Maverick and FR Utility Jeans step it up to 12 oz, 100% cotton for heavier outdoor conditions where durability matters more than stretch.

FR Canvas Work Pants — When Denim Isn't Enough

For workers who need more than denim, the FR Flex Canvas Stretch Work Pants are built from 10 oz, 87% cotton / 12% nylon / 1% spandex — a tougher construction that handles abrasion better and holds up longer in rough environments. Available in Navy, Grey, and Khaki. These are the picks for pipeline work, construction sites, and anyone who puts their pants through more punishment than a denim weave can handle.

FAQ

1. What's the difference between FR denim jeans and FR canvas work pants? 

The denim jeans — both stretch and utility styles — are cotton-based and better suited for moderate conditions or workers who want a more everyday look. The canvas work pants add nylon to the blend, which makes them more abrasion-resistant and better for jobs with heavy physical wear on the fabric.

2. Which FR jeans style should I pick? 

If you want stretch and a cleaner fit, go with the Basic or Fashion stretch jeans. If you're working outdoors in rougher conditions and need heavier denim, the Maverick or Utility jeans in 12 oz, 100% cotton are the better call.

3. Are these pants compliant for oil & gas and electrical work environments? 

FR cotton bottom wear is standard PPE across oil and gas, electrical utilities, and industrial construction. If your site has a specific PPE program or compliance requirement, check the garment specs against those standards or contact us before ordering.

4. Do FR pants hold their protection after repeated washing? 

Yes, as long as you wash them correctly. Use warm water, mild detergent, no fabric softeners, no bleach, no starch. Those products coat the cotton fibers over time and wear down FR performance. Low heat in the dryer, and always follow the care label.

5. Can I mix FR jeans with FR tops from NKE? 

That's exactly how these are meant to be worn. Any of the FR bottom wear in this collection pairs with NKE's FR shirts, hoodies, or outerwear for a fully compliant head-to-toe kit.

6. What sizes are available? 

Sizing varies by style. Check individual product pages for size charts. NKE cuts these for working — enough room to move, squat, and climb without the fabric fighting you.

7. Do you do bulk orders for companies or crews?

 Yes. Contact us at Onlinestore@nkesafetyapparel.com or call +1 (945) 253-8191 for bulk and distributor pricing.
