Need an extra lid? We've got you covered. These leakproof lids fit both the 18 oz and 32 oz stainless steel bottles and all the parts that touch your drink are 100% stainless steel. 

The silicone ring ensures your drink doesn't leak out, and the outside threading is BPA-free plastic that glides onto the bottle smoothly and quietly.

Here's how it works: the space between the inner and outer flask wall is evacuated, creating a vacuum (well, a partial vacuum anyway...). In order for heat transfer to take place from the outside world into your cold drink, or from your hot drink to the outside world, it needs nearby molecules to excite. If there aren't many molecules nearby, as is the case in a vacuum, the heat's energy can't easily be passed along, so your drink stays close to the temperature it was when you put it into the flask for a really long time. 

Simply stated, vacuums make great thermal insulation!

Got a better seal on my water bottles.

Bought a couple of these since I noticed my hydro flasks weren't keeping temperature well. Used these on two different bottles and noticed a significant difference. They also look sharper and seem more sturdy.
