Your local landfill will thank you when you upgrade to reusable bottles. This one holds 30 ounces, and is made of durable plastic for long-lasting utility. With a molded body to help with grip and a carrying loop built into the lid, it is easy to take anywhere you go. The flip-up cap stays attached so it will not get lost, while the bottle opening is wide enough to fit ice cubes and make refills easy. Everything is completely BPA free and top rack dishwasher safe. Do not microwave.
