I hadn't heard of using bamboo for clothing until just recently. These changing pads are made from bamboo and polyester. The bamboo helps to keep them germ free. I don't know exactly how this works, something in the bamboo I would think. However, it is very soft. I know soft is not something you would think of when you think of bamboo. At least I know I wouldn't but they are.
These changing pads are sold on Amazon at https://www.amazon.com/Waterproof-Baby-Changing-Liner-Antibacterial/dp/B01HYDH5GW. They really aren't that expensive either.
I can see that these pads would not irritate baby's skin because they are so soft. The color is nice too. It's a beige color that is really light so it shouldn't hold heat if you use it outdoors which is nice, especially here in Southern Arizona.
Have a great day!
