Description

DEWALT DST921-L Class 2 FR Long Sleeve T-Shirt

The DEWALT DST921-L Class 2 Modacrylic FR Long Sleeve T-Shirt is built for workers who need flame-resistant protection with high visibility. Made in the USA with global materials, this shirt meets ANSI 107-2010 high-visibility requirements and ASTM F1506 flame-resistance standards. The jersey-knit modacrylic/cotton/polyester blend is comfortable enough to wear all day, and the 10.0 cal/cm² arc rating gives you serious protection against arc flash.

The Hi-Vis Green background and reflective material help others see you in low-light conditions, whether you're on a roadway, in a plant, or on a construction site. This long-sleeve version adds extra arm coverage for tasks where you need to keep sparks and UV off your skin.

Compliant, Durable, and Comfortable

This shirt is designed to hold up to frequent washing and hard use while maintaining its FR properties. The modacrylic blend resists ignition and self-extinguishes, and the fabric won't melt or drip like ordinary synthetics.

Large Size Fit and Layering

The Large size offers a full cut that layers easily under outerwear or as a stand-alone shirt. Pair it with a Class 2 FR vest to increase visibility without sacrificing comfort.

10.0 cal/cm² arc rating – Meets ASTM F1506 for thermal protection.
ANSI 107 Class 2 hi-vis – Certified background and reflective material.

Modacrylic/cotton/polyester jersey knit – Comfortable, breathable, and FR.

Product Details

FR Construction That Works as Hard as You Do

The modacrylic blend is chosen for its balance of comfort and flame resistance. It holds its shape through repeated washings, and the high-visibility properties stay bright when cared for properly.

Layering with Class 2 PPE

For maximum visibility, pair this long-sleeve shirt with a Class 2 FR vest. The shirt adds a base layer of arc protection while the vest adds more reflective area and the combination meets ANSI 107 for most tasks.

How to Wash FR Clothing

Use liquid detergent and avoid chlorine bleach or fabric softeners, which can weaken FR fibers. Washing inside out helps protect reflective tape and keeps colors brighter.

I've been wearing FR shirts for thirty years. This one is the most comfortable I've found. The material is breathable and the fit is true. The hi-vis is bright even after many washes. It's held up well under tough conditions. Definitely will buy again.
