To make sure you order the right size….
Measure around the fleshy part of the limb in cm or inches approx 4 cm above the affected area, & make sure the cover is long enough
The cover will fit comfortably & form approximately a 1cm wide seal around your limb which acts as the waterproof seal.
For limb circumferences up to 27cm, choose a 40mm seal size cover, i.e. ML/M/40 (medium leg, medium aperture/40mm)
Up to 26cm limb circumference choose a 30mm seal size cover, i.e. SL/S/30 – short leg (medium on a child), small, 30
Over 27cm limb circumference choose a 40mm seal size i.e. SA/M/40 – medium arm, 40
FOR BABIES USE A SHORT ARM PRODUCT, FOLLOWING THE MEASURING ADVICE ABOVE
NOTE: The contact area should be as oil & hair-free as possible
