Wool is a wonderful fibre that can protect the
body in both warm and cold climates.
Wool is naturally a breathable fibre
and a temperature regulator.
When the wool fibre absorbs moisture, it produces heat. Wool picks up moisture in vapour form from the air, keeping you warm. Wool can absorb up to 30% of its weight in moisture without feeling wet or clammy. Tiny pores in the cuticle cells of the fibre allow water vapour to pass through the wool fibre.
Wearing wool is an excellent protector against hypothermia because of its natural way that it helps to regulate the body temperature. This condition can be extremely serious and can ultimately cause death. Hypothermia occurs when the body’s core temperature drops below that required for normal metabolism and body functions.
The reverse of cooling down when wearing wool occurs when you heat up – the moisture in your clothing passes into the air, cooling you down. When the body cools itself naturally through perspiration, wool absorbs the perspiration which in turns keeps dry air next to the skin. Wool is an amazing fibre that is also odour resistant.
The natural crimp or soft curl in a wool fibre adds bulk to a garment and will trap a large volume of air between each fibre. This adds extra to the already excellent insulation properties that wool provides.
So, is merino wool warm to wear?
Yes, most definitely for all the reasons given above.
Don't forget that merino is a breed of sheep. Merino wool is chosen for garments because it is very fine, soft and strong.
