YogaFit, the nation's largest yoga education company, now has a line of bamboo clothing that is extremely comfortable. The bamboo fibers are surprisingly soft, very breathable, and are naturally anti-bromic - meaning perspiration odor is limited.
Bamboo is one of the most eco-friendly plants on the planet. It is naturally pest resistant, so pesticides aren't needed. It is a grass that is one of the fastest regenerating plants around, and I just like the way it feels when I wear it.
I like the colors YogaFit offers and the styles are nice enough that they can go from mall to yoga class without looking out of place in either location.
