According to Super Eco, it depends. With the growing popularity of bamboo, eco-fabrics and "green"wear, the environmental-friendly clothing may not be quite as friendly as you assume. Here's why:

1. Chemically manufactured bamboo fiber is a "regenerated cellulose fiber similar to rayon or modal." And where are chemically-manufactured fibers created? In manufacturing facilities, most of which pose potential health hazards and damage to the surrounding environment.

2. A research team at Colorado State University recently found that, contrary to bamboo's finest selling points, the anti-bacterial qualities praised in bamboo fabric are found in many other fibers and are not unique to eco-friendly fabrics. What this means? If you're paying more for the deodorizing, antibacterial effect, take your money elsewhere.

3. Many bamboo fabrics originate in China, where labor practice is often suspect.

So how can you be sure your tee is green? According to the LA Times, check for the Oeko-Tek 100 certification, which won't be placed on a clothing label, but most manufacturers will post their certification on their site. The Oeko-Tek 100 is proof that your clothing is free of dangerous and potentially harmful chemicals.

Bamboozled? Don't be. Just remember to shop smart and do your research. You'll be living green in no time!
