Teeki makes leggings and other active wear items. I purchased a pair of lightish green pants with moons on them. Not only are they silky smooth but they are extremely comfortable. I could wear these pants for weeks. Made of recycled plastic bottles, I was surprised that you could make something so awesome out of plastic.
My only complaint is that due to the slickness of the material, they feel like they are falling down when I run, but for all t=other activities they were great.
