Because of a slight mixup, I have both the 14 oz and the 22 oz bottles, and one sport cap. The sport cap goes on whichever bottle I am carrying at the time. (I'd get another one, but it seems silly to pay shipping for just a cap!) The wee bottle went with me to Washington DC for the Women's March. If you are going to have a bottle banging against your leg all day, make it a Bubi. No bruises. The 22 oz is my go-to. Pink sport cap on purple bottle - looks like a mutant baby bottle, but it's MINE!! I love not having to worry about how much water I put into it before I stick it in the freezer. The big D-biner is brilliant. The bottle itself insulates pretty well too. I have not had it in hot weather yet, but in room temperature, I still have some ice hours after I take it out of the freezer.
If I were to change ONE thing, I'd make the sport cap tube (and cap hole) a bit wider. I want my water NOW, LOL
