This is a breast collar that is hand braided out of the highest quality 550 paracord.  It is very adjustable.  The rings are stainless steel.  It takes up on the side very simply with roller buckles.  I have attached trigger snaps to the sides and the bottom tugs to make it easy attach. 

 The colors of this breast collar is Brown.

There is a lot of room for adjustment in all of the sizes.
