The findings are consistent: Bamboo towels are four times as absorbent as cotton towels. If you want, you can test this yourself. Simply take a bamboo towel and a cotton towel of similar thickness. Drop them one at a time, in a bathtub of water. Clock how long each takes to sink to the bottom. You’ll see the bamboo sinks four times faster. So absorbency definitely makes our list of awesome bamboo towel benefits. The high absorbency of bamboo viscose makes it great for wicking away moisture when you get out of the tub, or when you take your towel to the pool. Our bamboo towels are god-sent to anyone who has ever used a cotton towel that barely absorbs any water at all. Good riddance, cotton towels!
