A very simple, but very effective product, the Enola Gaye armband is the industry standard for team ID in combat scenarios. Bullet proof, bomb proof, and visible to your team mates so you don’t start taking stray accidental shots.
Available in Red, Blue, Green, Yellow, and Orange.
Easy pull tab on the side removes the arm band super quick and super easy, but there is no fear of it falling off your arm – it is attached with wide strip of Velcro.
One size fits most. No guarantees if you have the arms of Thor.
