BPA free

Our lightweight, leak-proof glass water bottle is the safe, eco-friendly alternative to plastic bottles. Use for lunches, travel, yoga and every day hydration. Silicone sleeve provides non-slip grip and added protection, and design allows you to see contents inside.

As with any glass product, please use common sense when storing and handling, and avoid extreme temperature changes that will crack the glass. Handle with care when filling with hot liquids. Not intended for use in oven, microwave or freezer. Care should be taken to make sure bottle isn’t dropped or knocked over, especially near the mouth of the bottle where exposed glass is not protected by silicone sleeve. Best to keep cap in place when not in use. The silicone sleeve adds protection, but does not guarantee against breakage.

Care Instructions: Bottles and silicone sleeves are dishwasher safe (top rack recommended). Although our lids are dishwasher safe, research has shown that it is best to keep plastics out of high temperature environments like microwaves and dishwashers.
