Hand made by B Bar B in Blackfoot, Idaho.  10 ounce oiled harness leather with 4 pouches for antibiotics and 1 pouch for syringe.  The rope with snap in the picture allows the bag to be held at a 90 degree angle to the horse for easy access to antibiotics.  The medicine bag is on the left side and the right side is a regular 9"x12"x4" saddle bag.  The saddle bag has a reinforced upper front to maintain stiffness.  The gusset also has a double thickness rolled top for extra strength.  These are very well made bags and a much better product than is typically available.  A tiedown dee ring is located on the backside bottom corner of each bag.  Click on the other photos at the bottom of the page for more details.
