I consider myself a bit of a tumbler connoisseur, so when Influenster sent me this Gx bottle I was ready to put it to the test. First things first, this stainless steel bottle is so sleek, sporty and cool looking. I found it to be a bit heavy, and because of that I think it’s best suited for court sports, golfing or lifting weights. The double wall really worked to keep my drinks cold for a long period of time and the leak- proof cap rotates and locks to the side, which I found both unique and convenient. Unfortunately, this bottle is pretty wide and tall, so it won’t fit in a refrigerator water spout or in a car cup holder. It is however dishwasher safe, which is a major win in my book. Plus, the silicone exterior doesn’t sweat and ensures maximum grip. Overall, I think this bottle is a great addition to any athletes workout routine.
