JustWears' very own MicroModal Air fabric fibres are derived from sustainably grown, renewable European wood sources. Organic microfibres last longer than cotton, are CO2-neutral, bio-degradable and feel softer than silk. The MicroModal Air fabric is 50% more absorbent and breathable than cotton, drying is quicker and everything is kept pleasantly cool all day. These natural super fibres are anti-bacterial, helping to prevent body odour as well.
