I've never tried them personally but they're Canadian and have organic bamboo as an option (can't see organic cotton).
On another note I've been using my Lunapads monthly for 6+ years (well, I got a 22 month reprieve when I had the twins) and I love love love them. Granted, mine are pantiliners and I only use them for very light days or as a back-up to my Keeper but they're great. Other than a few stains and some ever so slight pilling of the fabric, they look the same as the day I bought them. I do occasionally use my one real 'pad' with the ric-rac and I don't mind it. Although I too have never tried other brands for a true comparison...
