Let them see that you're working for what you've got with this water bottle. It can hold 600ml of liquid and is light enough to carry anywhere, particularly the gym! It also comes with two different caps, so that when one is being washed, you're still good to go with the second one. A vibe is the feeling you get from another person - what they're like, what you feel they may be capable of. There are some types of people just don't want around - no bad vibes go with any outfit (and it's particulcarly not enjoyed in the gym, when all the motivation is needed!).
