Merino wool's best feature is temperature regulation by keeping you warm in the cold and cooling you when it's hot.
Merino fiber can absorb up to a third of its weight in liquid while retaining its best properties. Merino fiber is also breathable, which allows sweat to evaporate, keeping the skin dry.
With antibacterial properties, it locks in unpleasant odors when you sweat. This is the biggest advantage over synthetic fiber.
Merino wool fabrics are best for the first layer. Products made of merino wool fabric do not need frequent washing, but the fabric still becomes softer after the first wash. Merino wool is much finer than traditional wool, which makes products made from it soft, comfortable and non-itchy.
Although merino wool fabric is often associated with winter and cold weather, it is a great material for year-round use.
