To clarify, these have no special IR features. The glow is in the normal visible spectrum, which also shows up on NVGs. IR.Tools is the brand name.
For those who need the best, these US Flags use the highest performance glow material available and are then wrapped in cordura for long term durability. Indoor light will be good enough to give a small charge visible in the dark while purposefully charging with a source like a flashlight will give very prominent glow results. Made in the USA by IR.TOOLS. Hook fastener sewn on the back.
Measures: Approx 3.75" x 2.2"
