The Sireno Brief is similar to the Green Grass Trunks signature, the Eros Brief. Like the Eros brief, this brief has unique side cutouts to create a more daring look. They added a new element to the design: a gold sea shell on each side of the hip.

Their extraordinary swimwear is crafted from a harmonious blend of 78% polyester and 22% elastane. The fabric boasts a captivating iridescent layer, lending a mesmerizing double-tone iridescent effect that shimmers with an otherworldly allure.
