Learn about the thermal performance of our water bottle.
Thanks to our advanced double-wall vacuum insulation and copper lining, this water bottle minimizes thermal transfer to the absolute lowest level. In our tests, ice remained solid for over 30 hours! For best results, fill your water bottle completely with ice and keep the lid closed when not drinking.
Pro Tip: Pre-chill your water bottle with ice water for 5 minutes before filling for maximum cold retention.
