A new concept in full containment arrow rests the "disk" is stamped from space age closed cell foam that is unbelievably quiet, very durable, and unaffected by weather. The arrow is easily loaded from the side and the foam disk will not damage the arrows fletching. Two "disks" are available. One for carbon shafts and smaller diameter aluminums and the other for larger diameter shafts. The Whisper Disk will fit right hand or left hand applications.
