Wool is naturally 100% hypoallergenic because it resists bacteria, mould, mildew and dust mites, all of which can trigger allergic reactions. The definition Hypoallergenic is non-allergy producing. (The definition of non-allergenic is “having no tendency to provoke an allergic reaction”. Therefore it cannot really be said that any product is really non-allergenic).
Wool is breathable, allowing it to absorb sweat and release it as vapour, keeping the wearer cool and dry and so prevent the clammy, cold feeling experienced when wearing some types of synthetic clothing.
Wool never melts in a fire so it can’t stick to the skin like many common synthetic textiles; even cotton can catch light at 225°C, whereas the temperature needs to reach 570-600°C before wool will ignite. Polyester will melt at 252-292°C and nylon at only 160-260°C
