3M® Heat Transfer (Iron-on) Reflective Tape
3M heat-transfer (iron-on) tapes reflect bright white at night, while the fluorescent colors offer great daytime conspicuity as well.
3M heat-transfer tapes bond exceptionally well to nearly any porous or semi-porous material by penetrating into the fabric (Note: May not bond well to waterproof material - see instructions and also specifications)
They stretch with the material and are so light weight you'll barely feel their presence, and they are home machine washable (105ºF) and dryable. 3M silver exceeds ANSI Level 2 standards (500 Cd/Lux/sq.m) for reflectivity.
