Our briefs are woven from premium Lyocell — a soft, breathable, biodegradable fibre extracted from certified eucalyptus pulp. The result is a fabric that feels cooler than cotton, regulates temperature and keeps its shape wash after wash.
Which size should I choose?+
We recommend going with your usual underwear size. Each product page has a size guide with exact measurements. Between sizes? Pick the smaller one for a tighter fit, the larger for more room.
How do I wash the briefs?+
Machine wash at 30°C with similar colors. Use a mild detergent without bleach. Line dry — avoid tumble drying to preserve fit and fibre. Fabric softener isn't needed; Lyocell softens with every wash.
