Despite its form-fitting silhouette, the Icebreaker Women's BodyFit 150 Siren Cami assures day-long comfort and performance. The merino wool wicks away moisture, dries quickly, and naturally keeps odors at bay, while the hint of nylon and Lycra assure subtle stretch and durability. Not to mention, the adjustable straps provide a personalized fit, so you're able to layer it under or over garments accordingly.
