Medical grade merino wool offers the best that wool has to offer, and has been used successfully to treat diabetic pressure ulcers.
Qualities of this wool includes:
Temperature regulation- keeps temperature of skin at body temp
Absorbs 30- 40% of its weight in moisture wicking it away from the skin
Rounded fibres that do not irritate delicate skin like common sheeps wool does
Fibres are springy and allow the skin to breath- forming to the shape of area it is being used
