Made for your everyday adventures, our "Frankie" Merino wool tank top is a four-season staple. Made of Merino Wool with (m)Force core spun technology, this tank offers natural sun protection, wicks sweat, is quick-drying and doesn't retain odor. Crafted from ultra-fine 17.5 micron Merino wool (the finer the fibers, the softer the fabric), this tank is super smooth to the touch and feels great next to skin. Frankie the Tank features a racerback design and the popular, very flattering "fitted to flowy" silhouette.
