Blood Type Marker™

tactical multi-position marker 2-pack

The wise front-line soldier's practice of field-marking one's blood-group on the boot-heel (typically with duct-tape and felt-marker), inspired this Hazard 4® exclusive blood-type plaque. The 3-d injection-moulded rubber marker is far more durable than the traditional solution since it cannot be wiped off, scratched-off, or dissolved by most solvents. A more professional choice for a unit or individual operator in its appearance, it more importantly prevents mis-reading (imagine B+ becoming B- after some trail-wear). The form-factor allows multiple fast-mounting methods. In keeping with the on-boot tradition, weave them into boot laces, either horizontally, vertically or diagonally (slotted holes allow for different lace-hole spacings). Wear them like/with dog-tags (i.d. medallions) or on a lanyard around the neck. Use paracord to make them into a bracelet. Sew them onto clothing/gear or Velcro™ backing using the perimiter trench. Or clip them anywhere since they are sold with a durable aluminum black carabiner. They come in sets of two with one clip in a variety of subdued colors, and feature a raised guilloche pattern in the background to break up mud/ice. They can even be screwed, rivetted, grommeted, or nailed onto hard surfaces such as plastic cases, wooden crates, etc. to mark personal gear or a paramedic's blood supply. Also available in glow-in-the-dark. Specify blood-type when buying.

Pure Uitility and FormReview by Feliciano M
I love these markers, as they are so versatile, I have one on my boots, and the other attached to my Rocket. Durable, low key, and one more thing I don't have to worry about if I was in an accident or something where I was not able to speak. I may be overprepared and paranoid, but luck favors the prepared, and these little gems fit that bill in my mind. And it's a 2 pack! Can't go wrong there! (Posted on 1/11/2013)
SeargentReview by Bertil H
Good quality since it is made of rubber and can therefor easily wash of dirt. The good thing about that is NOT a patch is that you can move it from any gear you wear to another. If you get your chestrigg removed you still got your patch on you shoes. Good complement to your other blood-type patches on your uniform. (Posted on 1/9/2013)
