Yes. The Radians ST11B is an ANSI/ISEA 107 Type R, Class 2 short-sleeve safety t-shirt — the visibility class designed for workers exposed to roadway traffic and busy work zones where they need to be clearly seen. Type R means it's built for roadway/right-of-way use, and Class 2 provides more high-visibility background fabric and reflective tape than a Class 1 garment. It's made with Max-Dri™ moisture-wicking mesh, has a black color-blocked bottom that hides dirt, and comes in Hi-Vis Green or Hi-Vis Orange with free shipping.

The Radians ST11B meets ANSI/ISEA 107, Type R, Class 2. Type R means it's intended for roadway/right-of-way environments, and Class 2 is the mid visibility level, requiring more high-visibility background fabric and retroreflective tape than Class 1 for use around moderate-speed traffic and complex backgrounds. It uses 2" reflective tape as one horizontal stripe around the torso.

Max-Dri™ is Radians' moisture-wicking mesh fabric technology. In the ST11B it's an arid Birdseye mesh made of 100% polyester that pulls sweat away from the skin and allows maximum breathability without sacrificing durability. The wicking action improves hot-weather comfort and makes the shirt feel cooler during extended wear, while keeping the garment lightweight.

On the Radians ST11B, the 2" reflective stripe is adhered by heat transfer rather than sewn on. The tape is stretchable, so the shirt flexes and wears much more like a regular t-shirt — softer, with no stitched seams under the reflective material to chafe or stiffen the fabric. This improves comfort and range of motion compared with traditional sewn-on reflective tape.

Class 2 (like the Radians ST11B) is required when workers are near moderate-speed traffic — typically roadways where vehicles move faster than 25 mph — or in work zones with complex backgrounds that make a Class 1 garment insufficient. Class 2 provides more high-visibility fabric and reflective tape than Class 1, but less than Class 3, which adds sleeve striping for the highest-risk, high-speed or low-light work. Choose Class 1 for low-risk parking or warehouse settings, Class 2 (the ST11B) for general road and construction work, and Class 3 for highways and night work.

The Radians ST11B is available in Hi-Vis Green and Hi-Vis Orange, both with a contrasting black color-blocked bottom, in sizes M through 5XL. It's a short-sleeve crew-neck t-shirt with a single upper-left-front (left chest) pocket and one horizontal reflective stripe around the torso. Free shipping is included.

Yes. The Radians ST11B is built for heat: its Max-Dri™ arid Birdseye mesh is highly breathable and wicks moisture away from the skin, which improves hot-weather comfort and makes the shirt feel cooler. The 100% polyester mesh is lightweight and durable, and the stretchable heat-transfer stripe lets it move and wear like a normal t-shirt rather than a stiff safety garment.

The Radians ST11B has a rated service life of 25 washes maximum — after that, the high-visibility fabric and reflective performance may degrade below the ANSI/ISEA 107 Class 2 requirement, so the garment should be replaced. It's 100% wicking polyester Birdseye mesh, and the heat-transfer reflective stripe is stretchable and integrated into the fabric.

Yes. Industrial Safety Products offers optional custom logo imprinting on the Radians ST11B, with a minimum order of 24 garments and a free set-up fee. Pricing is per location — for example, a one-color front or one-color back imprint is $2.50 per location, and a one-color imprint on both sides is $5.00. Available imprint locations include the left chest pocket and the center back. Orders below the 24-garment minimum ship as non-logo items.

By design. The Radians ST11B's upper-left-front pocket deliberately has no reflective material on it so that a company logo or corporate imprint can be applied cleanly to the chest. The garment still meets ANSI/ISEA 107 Class 2 because the required reflective coverage is provided by the 2" horizontal stripe across the torso. This lets employers brand the shirt without compromising its high-visibility rating.

The Radians ST11B has color blocking at the bottom — a solid black lower section beneath the hi-vis body. The black bottom helps hide dirt, grease, and stains that would show on the bright fabric, keeping the shirt looking cleaner over a workday, while the upper body and the 2" reflective stripe still provide the required ANSI/ISEA 107 Class 2 visibility. It's a practical style choice common on hi-vis work shirts.
