These are just some of the beneficial characteristics of woolen garments:
Effective all-weather protection
Renewable and environmentally friendly
Tough and elastic
Easy to dye
Low allergy likelihood
Naturally flame-retardant, with a far higher ignition threshold than many other fibres, will not melt and stick to the skin causing burns
Better UV protection than most synthetic fibres
