Soft and stretchy women’s bikini underwear with a modern slim fit, the Siren Bikini Arena features our 150gm jersey corespun merino wool blend and a go-to modern shape that makes for the perfect everyday underwear. Our corespun fabric uses nylon fibers wrapped in merino wool for added strength and durability that retains next-to-skin softness. The Siren offers bulk-free comfort at the waist and leg openings, and the side seams are moved forward for chafe-free movement.
