We've blogged about bioMe clothing's committment to the earth (100 percent organic cotton, sweatshop free) and our love of their use of strong graphic letters and matching animal prints. And now the company has released a limited edition polar bear T-shirt ($32 and free shipping). In keeping with the earth-friendly vibe, 20 percent of the proceeds will go to the Detroit Zoo, which has been breeding polar bears since 1928. As well, the T-shirt uses undyed/unbleached cotton and is shipped in biodegradable green film bags (which according to the company take as little as 9 months to biodegrade).
