We tested it, and this is not a 10-gallon hat. A lot of soaking wet hats later though, we can confidently say that this hat is just as true Texan as a 10-gallon hat, and you can still be a cowboy. Or a Cowboy. Or a Texan, or a Longhorn, or a Red Raider, or an Aggie, or even a Hippo (shout out to Hutto High School just outside of Austin). Either way, show your Texas pride with this maybe 1-gallon hat that still allows you to fly your Texas flag proudly.
