The Contigo Thermalock Glacier lies somewhere between an insulated thermos and a daily water bottle. Contigo markets this product to keep heat out and cool drinks in, but the bottle can be used the other way as well — keeping hot drinks warm for long periods of time. Much like the Avex Brazos Autoseal, the Contigo is easy to clean and does not retain flavors, making it a great vessel for sports drinks or iced tea. Similar to the Avex, the lid is overly complicated and has many plastic parts that seemed excessive and prone to failure.
The Thermalock Glacier is offered in two new colors this year! Check them out below.
