Product Overview

I recently tried the Thermoflask 24oz Spout Bottle 2pack Mayan Blue, Black and I must say Im impressed. The bottles are made of stainless steel and have a vacuum insulation that helps keep your drink cold for up to 24 hours.

The best part about these bottles is the lid. Its a leak proof spout lid that allows for easy one handed drinking or pouring. This means you dont have to worry about spills or leaks while using the bottle.

Another great feature is the double wall design. This prevents condensation from building up on the outside of the bottle which keeps it looking clean and new for a long time. The 18/8 food grade stainless steel also makes sure that its BPA free, toxin free, and wont rust.

The wide mouth of these bottles also makes them great for adding in ice cubes or cleaning out easily if need be. The product care instructions state that theyre machine washable so you dont have to worry about any extra maintenance either.

Overall, I highly recommend this product for anyone looking for a reliable water bottle that can keep their drinks cold all day long. The vacuum insulation technology does its job perfectly, and the leak proof lid design means no more spills or messes. Plus with its stylish Mayan Blue/Black color, its perfect for taking with you on any adventure!
