Beech fibre, durable and breathable
Biolight is a plant-based fibre that gives garments unique characteristics. Derived from the cellulose of beech plants, this fibre is smooth, soft and bright, and provides an extremely pleasant touch.
BIOLIGHT is characterised by its breathable properties and its ability to retain moisture (twice as much as cotton). Thanks to its structure, BIOLIGHT fabric helps to keep the skin cool and dry.
