Yes, for comfort, a sharp look, and enhanced daytime/low-light visibility. The Fierce Safety SN300B is a black short sleeve work shirt made of microfiber polyester moisture-wicking fabric, with 2" wide silver reflective tape and contrasting trim in a 360° configuration so the wearer is visible from every angle. The black body looks professional and hides dirt while the reflective striping adds conspicuity. Note it is an enhanced-visibility shirt (black body with reflective tape) — it is not ANSI/ISEA 107 certified, so it's ideal as a comfortable, good-looking hi-vis work shirt, not a substitute for a rated safety vest where a compliant garment is required. Offered in sizes M–2XL with free shipping from Industrial Safety Products.

No. The Fierce Safety SN300B is an enhanced-visibility black shirt, not an ANSI/ISEA 107 certified garment. Neither the product listing nor the manufacturer spec sheet lists an ANSI/ISEA 107 rating, a Type (R/O), or a Class (1/2/3). Because it has a black background, it cannot meet the fluorescent background-color requirement of ANSI/ISEA 107 regardless. It uses 2" silver reflective tape with contrasting trim (360°) to boost visibility, but for roadway, right-of-way, or any work that mandates a certified Class 2 or Class 3 garment, you need an ANSI/ISEA 107-rated vest or shirt. The SN300B works well as a comfortable hi-vis work shirt or as a layer under a certified vest.

The Fierce Safety SN300B is made of microfiber polyester moisture-wicking fabric. Moisture-wicking means the polyester fibers pull sweat away from the skin to the outer surface where it evaporates faster, helping keep the wearer dry and comfortable through a full shift. The material is also breathable and lightweight, promoting air circulation that reduces worker fatigue and heat hazards, and the manufacturer notes it reduces heat and feels cooler — which is why it's marketed as an all-day-comfort hi-vis work shirt.

The Fierce Safety SN300B has 2" wide silver reflective tape with contrasting trim, arranged in a 360° pattern so the wearer reflects light and stands out from all sides in low light. On the black body, the silver tape and its contrasting trim create high contrast for better worker visibility. Keep in mind this reflective striping enhances conspicuity but does not make the shirt an ANSI/ISEA 107-certified garment — it is an enhanced-visibility shirt, not a rated Class 2/3 vest.

The Fierce Safety SN300B is offered in black and in sizes M, L, XL, and 2XL (part numbers SN300B-M, SN300B-L, SN300B-XL, SN300B-2XL). It has a crew-neck comfort fit and is cut as a standard short-sleeve work tee, made from lightweight, breathable microfiber polyester so it feels cool and comfortable on the job.

Yes. Industrial Safety Products (industrialsafetyproducts.com) sells the Fierce Safety SN300B with optional custom imprinting, with a minimum order of 24 garments. Available methods include screen printing, heat transfer, and embroidery. If an order doesn't meet the 24-garment minimum, ISP ships the shirts as non-logo items. The shirt comes in black, sizes M–2XL, with free shipping.

The Fierce Safety SN300B is best for hot-weather and high-exertion work where comfort, a professional black look, and enhanced visibility matter but a certified garment isn't required — such as warehouse work, landscaping, general labor, facilities and grounds crews, delivery, or as a breathable hi-vis layer worn under an ANSI-rated vest. Its moisture-wicking, breathable microfiber polyester keeps workers cool and dry, and the 360° 2" silver reflective tape improves conspicuity in low light. Because it is not ANSI/ISEA 107 certified (and has a black, non-fluorescent body), it should not be relied on for roadway, nighttime, or low-light traffic work that mandates a rated Class 2/3 garment.

It depends on the need. Versus a standard work shirt, the SN300B is worth it: its microfiber polyester moisture-wicking fabric dries faster and breathes better than cotton, its black body looks professional and hides dirt, and its 2" silver reflective tape in a 360° pattern adds visibility a plain shirt lacks. Versus a traditional yellow/lime hi-vis vest, they serve different purposes — the SN300B is a comfortable, wearable hi-vis shirt, but it is not ANSI/ISEA 107 certified and its black background can't meet the standard, so it doesn't replace a rated Class 2/3 vest where compliance is required. Many workers choose the SN300B for comfort and looks and pair it with a certified vest when the job calls for one.
