I own two of these bottles and use them for bicycle touring. I had problems with other bottles; because the drinking port being exposed, the port would get filthy. These bottles completely seal off the drinking port which stays perfectly clean. However, I need to get off the bicycle to use them because of the procedure for opening the port. So, if you must drink while pedaling, I could not recommend them. A well made bottle with a unique design that does not allow the bottle to airlock while you are drinking. Very nice.
