Favorite green clothing or gear?

For Earth Day this year, Rock/Creek gave our annual Sustainability Award to KEEN for work they've been doing to clean up their shoes, sandals, and bags. Check out the full story here at Rock/Creek.
What's your favorite green gear? Recycled polyester fleece from Patagonia? Recycled rice paper bags from KEEN? Running shoes from END (Environmentally Neutral Design)?
