People use many ways to carry their drink bottles. We believe the hips to lips drink bottle clip is the best bottle holder by far. It has been tested in real work and exercise situations for almost two years. The clip has been modified over time to become the most versatile and ergonomic bottle holder available. Those who did the testing are people who take their water bottle with them all the time no matter what. The guy below collecting rocks is a stone layer. He has been testing the clip from the very first prototypes. Here are his own words.

This device is just amazing. I was always fussing about keeping my water bottle handy because I'm out in the heat. With the bottle clip I got used to having my drink hanging from my jeans pocket in no time, I don't even know it's there until I need some water. The best part is that it just stays there. You have to somehow bump it upwards or tip it right around so that the drink bottle is horizontal before it will fall off, but when you want to take it off for a drink it just comes off easily
