best on the market

absolutely love these bottles. we have a total of 6 at the moment. the smaller ones we use in our camelback fanny packs when we go hicking. The larger ones we use when on the go. these keep stuff colder for longer than any other on the market. i can leave it in the car in the hot summer, come back several hours later to a cold drink.

i finally can keep my Duet Coke cold and fizzy!!

This was my second try for a bottle for my coke. I am thrilled with it. No, it won't keep it overnight, but it works great for 8 hour shifts at work. I can leave the bottle in the car on a hot day while I shop and come back to perfect Diet Coke.

I have advanced arthritis so it is difficult for me to use some types of travel mugs because i cant get the top off. This top was easy to use and i have been able to get the top off every time i used it.
