always slips out

Unfortunately, the protection is only foldable. On one side are magnets, on the other not. I have then sewn a Velcro closure on both sides. So the chest protector does not go off when romping and rolling. Our thoroughbred, who is very sensitive with his skin, no longer has any open spots from closing the fly blanket. He also does not sweat under the chest protector. The only shortcoming is really that he is not to close at the bottom, but this can be corrected with a few handles.
