For those of you unsure as to why Merino is so spiffy, read on...!
Merino is excellent at regulating body temperature, especially when worn against the skin. The wool provides some warmth, without overheating the wearer. It draws moisture (sweat) away from the skin, the fabric is slightly moisture repellent allowing the user to avoid the feeling of wetness. Merino wool retains warmth when wet helping wearers avoid hypothermia after strenuous workouts (climbs) or weather events.
