These Small 4″ x 2″ Chest Patches are a great tool for first responder identification. They feature embroidered letters and are available in 3 different color combinations. The patches are perfect for tactical vests or other outerwear. Patches come with a plain back to allow the patch to be sewn on. A hook option is also available for an extra cost. This allows the patch to be paced on a vest or jacket already outfitted with the loop option.
