Seamless and breathable, the Sia Brief is designed for both outdoor adventures and daily life.

We've used super soft tencel rib fabric that is kind to sensitive skin, plus the seamless circular technology eliminates chafing. Ergonomic panelling, including tighter construction around the waistband, offers lightweight support and optimal comfort. From hikes in the highlands to days on the beach, the Sia set is the best base for any outfit.
