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, a phenomenon known as wicking. The fabric is slightly moisture repellent, allowing the user to avoid the feeling of wetness -from Wikipedia.
Enough said, this jersey will be one of my favorites.. and I can’t wait for the next ride to wear my new helmet! Thank you to my lovely wife 🙂
