Don't just sip, chug. The 1.5L Thrive Chug Bottle is our largest drink bottle, built to keep you hydrated on even the harshest days. Manufactured from Tritan Renew plastic, a highly durable and lightweight plastic which is BPA, BPS and BPF free and easy to clean. The leak-proof screw lid protects a wide spout silicone chug cap. When opened a spring-loaded mechanism smoothly flips the lid back and holds it in place while you drink. The large soft silicone carry handle provides a comfortable grip, while the non-slip base keeps the bottle steady. CamelBak products are backed by the Got Your Bak lifetime guarantee.
