Trunk in Organic Cotton Rib - Tar / Sand is a modern and minimal European cut designed for comfort, movement, and everyday wear. The body fabric is GOTS-certified organic cotton rib in Tar, with a small amount of elastane added to maintain shape and allow natural stretch. The rib knit provides flexibility without bulk, making the trunk breathable, soft, and stable throughout the day.

The leg openings are finished with cotton binding for a secure edge that stays in place without digging or riding up. This helps the trunk sit clean under clothing, holding comfortably without the need for constant adjustment. The waistband is made from rich cotton for support, finished with a minimal stone.kin logo quiet, refined, and deliberate.

Trunk in Organic Cotton Rib - Tar / Sand offers a mid-length profile that provides coverage with a smooth, tailored fit. It feels supportive without compression and soft without losing structure. The organic cotton fabric is naturally breathable and works well for warm climates, daily movement, and sensitive skin.

Tar is a deep, grounded charcoal tone, balanced with a Sand waistband for a neutral contrast that remains subtle and versatile.

No synthetic. No toxins.

No loud branding.

Just organic cotton, a clean silhouette, and a fit designed to be lived in.
