Hands down the best bottle
I have several of these. They are my go to bottle for biking and everyday use. They keep cold drinks colder for longer that typical bottles. The positive of jet valve keeps them leak free in a bag or pack. The jet valve flows very quickly which is ideal during exercise. These things last a long time as well. I just use mine for water and occasionally sports drinks. Be sure to wash after sports drinks or the plastic will hold onto the flavor for a while.
