Don't just sip, chug. The 1L Thrive Chug Vacuum Bottle is built to keep you hydrated on even the harshest days. Manufactured from stainless steel, its double wall vacuum insulation keeps your drinks the perfect temperature. 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. BPA, BPS and BPF free and easy to clean, CamelBak products are backed by the Got Your Bak lifetime guarantee.
