Hemp is naturally moisture-wicking
Hemp can absorb up to 20% of its own weight while still feeling dry to the touch, comparative to polyester which can only absorb a maximum of 6% before feeling wet. This is particularly important for fabric that is in direct contact with our skin such as clothing or bed sheets, as perspiration is quickly absorbed and released.
A fabric's ability to absorb and release moisture/sweat quickly (before bacteria begins to feast) is called moisture wicking. This is the process of wicking moisture away from the skin and to the edge of the fabric where it can evaporate. The better a fabric is at this process, the less moisture it retains and therefore the less odour-causing bacteria (body odour) can build up.
The porous nature of the hemp fibre means it’s naturally highly breathable and has natural moisture-wicking properties.
Many synthetic fabrics are exposed to chemicals (odour neutralising fabric finishes) in order to reduce odour build-up, whereas hemp’s natural breathability and moisture-wicking properties reduce and prevent odour from occurring, without the need for chemical treatments.
