When you choose a Kishigo shirt, you’re tapping into a legacy of safety‑first apparel that’s trusted by industrial crews across the country. The F506T Unisex Tall FR Long Sleeve T‑shirt is one of Kishigo’s most popular workwear pieces because it blends flame‑resistant protection with a comfortable, breathable knit that moves with you. Crafted from a 6‑6.9 oz mixed‑fabric blend of modacrylic, lyocell and twaron, the shirt meets ANSI/ISEA 107‑2020 Class 3 requirements and offers a CAT 2 arc rating for added peace of mind on the job. Its high‑visibility side panels and reflective accents keep you seen in low‑light conditions, while the left‑chest pocket provides a handy spot for ID or tools. You can personalize each shirt with screen printing or DTF, and we support low minimums for most jobs—just remember screen printing starts at a 24‑piece run. Whether you need a handful for a small crew or bulk custom t‑shirts for a nationwide rollout, the Kishigo F506T delivers the durability and safety you demand, with a professional look that stands out on any site.
