Blankets and wraps can be used on any part of the body. If you are using the wrap on the arm, back or leg area, cover the area and hold the Farabloc in place using a tensor/ace bandage. Make sure the tensor/ace bandage stretches with your body and does not stop circulation. Blankets can be used under or over the body when sleeping. If you sleep on your back it is common to place the blanket under the sheets. View sizes below
