The Horse Blanket is designed to be worn for long periods of time in the middle of the summer when it is hot.  You are able to put a winter blanket over the top of it without loosing  the magnetic therapy effects. The blanket is designed so the magnetic straps follow the meridian lines and acupoints of a horse providing optimum results. Each blanket comes with 6 straps at various lengths ( 2-20" w/10-4,000 gauss magnets  and 2-24" w/12-4,000 gauss magnets and 2-32” w/16-4,000 gauss magnets). The magnetic straps are removable for placing where symptoms need to be treated.  Straps are available in all north (N) only.
