Any harness that has at least a 1 3/4 " opening will do. If using O rings type as long as there is an opening 1 3/4" wide. The thickest part of the Share is about 1 3/4" wide. So as long as opening is that wide it should fit thu it.

Some of the O rings type also have openings wider than the O ring holders. The Share will go thu that and not need any O rings. On our review on the Leather Rider Luxe there is a pic of what it would look like poking out of just the harness with no O rings used. The brown on is 2 " wide and the flesh color (VC Bandit is 1 3/4". The Share should go thu that also.
