Overview: Hydro Flask has three new sizes of their very popular wide mouth flip cap. They are now offering 12 ounce, 16 ounce and 20 ounce models. They  previously  made an 18 ounce but it was dropped. These terrific flasks now align with the most popular coffee sizes that you find at your local coffee shop.

These are great items as far as at your campsite and also great items as far as before you jump in your car and heading out to your campsite for a nice little companion drink on the way.
