Hemp is known for its superb moisture-wicking, breathable and hypoallergenic properties. It is also one of the strongest natural fibers. For centuries, hemp has been used to make strong ropes, jute and bags. The special mesh-pattern knitting also makes them breathable. The combination of moisture wicking and breathing makes them perfect for humid and warm weather and for those, whose activities require much effort and produce sweat.
