When it comes to comfort, your next-to-skin garment is one of the most important for making sure you're going to be comfy all day during various activities. It should also arguably be your safest layer—it's your last line of defense before hazards reach your skin.

Enter the comfiest piece of safety equipment you'll ever own: the US Army's FR Tee. An expert at moisture wicking, breathability, flexibility, quick drying, and no chafing. It's the shirt you'd want to have on when you can't change it out for the next couple days out in the desert.

The US Military even went so far as to set standards for moisture wicking capability, which this shirt passes with flying colors: wicks moisture 3" outward in 3 minutes, and 90% of the wicking properties retained after 50 washes.

Why FR?

expectations might be set a little bit high here sometimes - it's not going to provide a force field against an inferno, but it will harmlessly smolder away and protect the surface beneath it, without melting or dripping. This means both fire and hot objects like suppressors or muzzles aren't going to work their way to your skin giving you nasty burns. An insurance policy at the least, and a skin-saver at it's best.
