I ordered 2 of the 8oz water bottles. I’m not gonna lie, they need to be twisted on pretty tight so as not to leak, but once you have it right, you are good to go. Not bouncy or annoying at all.
Honestly it’s been a long time I was looking something like that you can hang your bottle while You’re running finally I found that and it really is not shaking and and is easy to kill me when you’re about
Perfect for me right now since I am not running or working out hours at a time anymore. I don’t even notice they are there when I am moving. If I ever get to the point where I can run longer distances then I will add more of these bottles.
I've tried many running water bottles from other brands and they always leak. The 2nd generation version of this water bottle (with the orange mouthpiece) did not! It also was easy to attach and access during the run, held snug to my waist, and didn't bounce. (Note it's a lot of weight for the standard SPI belt, so for no bounce you either need to make it fairly tight so that the elastic wont stretch on each step, or put the bottle holder in your waistband. Both easily solvable).
Love the bottle and it’s my 5th one I have ordered. Great for runs and I don’t even feel it on me, even when I use two of them.
