Synthetics petro based fibrics really can't match the properties nature has harmonized through eons. The merino wool and hemp fabrics complement the human body. They are in sync with who we are, what we do and where we do it.
The hemp is slightly more comfortable compared to the wool because it resembers the familiarity of cotton and has 3% spandex, so it stretches more. But it's a couple grams heavier and slower to dry holding sweat and water longer.
Both fabrics are pre-shrunk
