This black Smartwool Merino 150 tank top is made of 87% superwash Merino and 13% nylon. It is in great condition. In person it is jet black, on camera the image is lightened and shows every tiny speck of fizz. This athletic tank makes a great base layer and will last for years. From SmartWool: Our line of Classic All-Season Base Layers apparel is full of ultra comfortable layers made for life on the move. We made our Classic All-Season our most versatile and durable 150g fabric yet by wrapping super-fine Merino fibers around a nylon core—helping to keep your new favorite shirt around from crag to camp to canyon with Merino wool still next to skin.
