Description

Soft viscose stretch fabric and a clean low-rise waist create an understated everyday trunk.

A quiet trunk cut close to the body.

The silhouette stays deliberately minimal: a narrow black waistband, a shaped front pouch and a short square-cut leg. Subtle tonal texture shifts across Black, White and Blue, while a small leather-look BSZN badge introduces one restrained point of contrast.

Viscose-rich stretch fabric feels smooth, breathable and fluid against the skin. The low-rise waist and close leg reduce bulk under trousers, while the lined pouch and full rear keep the trunk practical for daily wear.

Design details
