Make a splash with our Siena brief. Both sporty and stylish, this brief is sure to have you stand out from the crowd in and out of the pool. If that hasnâ€™t already ticked your boxes, then this here is sure to. The Siena brief is made from our innovative Ecolastâ„¢ fabric, composed using recycled fish netting and other waste removed from our oceans. Ecolastâ„¢ is not only helping protect our environment for future generations, but has also proven itself to be more durable and resilient to chlorine than other generic swimwear fabrics. It really is making waves.
