Start with your chest and sleeve measurements and match them to the size chart on each product page.

• Allow room for base layers and full range of motion.
• Fit varies by style: knit Henleys and crews often feel more flexible; woven twill or denim is more structured.
• 100% cotton styles may shrink slightly after laundering; review the product description for fabric and care notes.
• If you’re between sizes, sizing up can help with reach and layering.
• Check the product page for return and exchange details in case the fit isn’t right.

On many listings, you’ll see “NFPA 2112” and “CAT2.”

• NFPA 2112 refers to a commonly used standard for flame-resistant garments intended to help reduce burn severity during short thermal exposures.
• CAT2 is an arc‑flash PPE category used in many workplaces; the specific arc rating varies by garment.
• Details can differ by shirt, so review the product description and garment labels for exact ratings.
• When in doubt, follow your employer’s safety requirements and choose items that list the standards your job needs.

For warm conditions, lighter fabric weights and breathable knits can feel more comfortable.

• Scan titles for weights like 5.5 oz, 6.25 oz, or 7 oz.
• 100% cotton and lightweight blends can offer airflow; knit (Henley or crew) construction may feel cooler than heavy twill.
• Lighter colors may retain less heat than dark shades.
• Still match any required standards (e.g., NFPA 2112, CAT2) shown on the product page.
• Comfort depends on climate and activity, so comparing fabric weight and style notes across listings can help you find a good balance.

Caring for FR shirts properly can help maintain their performance, but care needs vary by fabric. Always follow the garment’s care label.

• Wash separately from heavily soiled items and with like colors.
• Use a mild detergent; avoid bleach and fabric softeners, which may affect FR properties.
• Turn shirts inside out and close buttons before washing.
• Dry on low to moderate heat and remove promptly; excessive heat can impact fit and feel.
• Check the product page for any item‑specific instructions provided in the listing.

Several FR shirts on this page call out welding use in their titles.

• Consider long sleeves and heavier weights (e.g., 7 oz or 9 oz) for additional durability in tough conditions.
• Verify any required standards on the product page (e.g., NFPA 2112, CAT2) if your workplace specifies them.
• Structured woven shirts can help with abrasion resistance; knit styles may offer easier movement—choose based on your tasks.
• Darker colors can help hide metal dust and grime between washes, though visibility needs may vary by jobsite.
• Always pair garments with appropriate PPE and follow your site’s safety guidelines.
