Where Did They Get Such Wonderful Toys?

At DCV08, I participated in a top-notch and very well represented event in Vancouver.
Part of their sponsorship deal included an event t-shirt with the event logo and the front, and sponsors on the back. Simple event schwag you say? Nay - these guys did one better - they had shirts made of Bamboo instead of Cotton.
I've not felt another t-shirt as soft as the eco-friendly shirts Dave and his crew had made.
Any ideas on Alberta vendors for the same?
