This sling didn’t work very well for some of my coffee cups. When the sling sits on your hip, it sits at an angle. It also tends to move a lot as you walk or bike, which can lead to some spillage. Only use this on bottles you trust not to leak—it won’t work well with Yeti(the magnetic lid type) tumblers, and some snap-close coffee mugs/waterbottles. Because it moves around so much, it especially doesn’t work well on a bike. I have use for it while hiking, but overall I’m neutral about how well this product preformed.
