Our borosilicate glass water bottle has time markers on one side and ML markers on the other side printed directly on the glass bottle. You will only need to refill it once in the afternoon to hit your minimum daily water intake goal! Use this water bottle at home, office, take it to the gym or anywhere really! Our glass water bottle comes with a stylish silicone sleeve to offer you additional protection and to provide an extra grip to the bottle. The sleeve is removable, so you can use the water bottle with or without it. We are including an extra lid so you can use the bottle for a longer period of time (just in case you misplace the other one). The bottle has a wide mouth, which allows you to use this hydration bottle as a water tracker bottle, or a blender bottle / shaker bottle to blend liquids with other ingredients, as well as an infused hydration water bottle to infuse your water with fruit and such. The wide mouth also makes it easy to wash the bottle. It is reusable, leak-proof, and safe to use. What are you waiting for? Get your 32 ounce water bottle today!
