I absolutely love that fits in both the BlenderBottle Classic and the SportMixer for compact traveling. I have been using mine when I know I will be away from the house for a while or working out in the afternoon. I just put it in my BlenderBottle Original and put them both in my gym bag. Now that you know (as if there was any question) how awesome they are here is how to enter!
