This was a gift for my son's fiancee via her request. She absolutely loves it because of the combined cap- both screw on and sport top combined as well as it keeps the water cold longer then one she had previously. I highly recommend this canteen.
I've been looking for a canteen that doesn't require removing the entire cap to drink out of it and this is the closest anything has come to what I want. You do have to unscrew the top a little bit for the water to flow out of the sport top. Would prefer a flip top where I can drink like I normally do out of a glass instead of it pouring into my mouth, but this is a good intermediary until someone makes what I really want.
