Boody is as soft as your favorite pajamas, but performs as high-quality activewear. Stay cool in the summer and warm in winter, without bulk. Bamboo fiber is lighter and softer than cotton and perfect for layering. No one likes being clingy. Unlike traditional cotton basics, Boody will keep its distance as bamboo fibers prevent static build-up. As you take a deep breath, your Boody Eco-Wear will too. Bamboo fiber has micro-gaps, which pull away moisture and keep air flowing.
