Worried that when you're injured and bleeding profusely with no idea where your blood type patch is? The best way is to wear more blood type markers that would ensure that any medic will get your blood type right. In the battlefield, there will be a tendency to lose such markers, and thus the need to have blood type markers that can easily installed in the most visible and obvious areas in your body.

Hazard 4 Tactical Gear, the military division of Civilian Lab, a company that specialises in outdoor, extreme sport, and travel gear, have released their Blood Type markers that would allow you to install such markers in many areas. These are 3-D injection moulded rubber makers that are more durable and rather than rely of ducktapes or velcro tapes, have holes that you can allow you to install with your boot laces, lanyard, zipper, or even used to mark blood supplies in boxes or crates.

Available in 2-pack kits, you can have colours to choose from to fit the loadout you have. These are available for US$8.88 or US$8.99 for the glow in the dark version.

Whilst made with the soldier in mind, this is also much useful for those who are into extreme activities. Outdoors people would love to have this. We highyl recommend these, but don't overdo yourself stuffing most of your clothing with these, people might think your name is a Blood Type.
