PRODUCT DETAILS THE TANK TOP - LIGHTWEIGHT, BREATHABLE, AND GREAT FOR LAYERING. Tucked in, or worn out, a tank top should hug to your shape. It should reach down far enough to avoid that uncomfortable feeling you get that too much is showing when you bend over. No cable guy here. Oh, and did we say it feels great, too? Why Bamboo? Why Bamboo Base Layers? Boody is all about affordable luxury, crafting everyday essentials and underwear from viscose derived from bamboo. The result is a silky smooth base layer that keeps you cool and comfortable with seam-free stretch. Our bamboo fabric maintains its shape and is great for sensitive skin. Bamboo fibers are naturally smooth and round with no sharp spurs to irritate skin.
