I believe the previous two answers to be incorrect. First, Jase is a millionaire and likely wouldn’t be caught dead in a cheap $4 knit cap. Secondly, he lives in Louisiana were it is very hot and humid for much of the year. He is likely wearing the beanie more as a fashion statement and style and also to accommodate shoulder-length hair. In that he seems to have more of a sense of style than the other brothers, my guess is that the beanie is at least a microfiber, and possibly cashmere or custom-made for longer length. There doesn’t appear to be much of a ribbed pattern at all and looks very light-weight, which would best fit with the ambient weather conditions. Your best bet would be to start by searching for cashmere beanies in your browser. Also, the “Jase beanie” appears to be a rich midnight blue color which might not be available at retail. Cashmere is much thinner and lighter weight than traditional wool. You could easily pay from $70 to $300 for a cashmere beanie. Possibly more if it were custom made.

The "freebie" fleece beanies worn by Jase are by Under Armour with a customized UA logo and style specifically for the Robertson clan as part of their Duck Dynasty endorsement deal. Similar styles available at underarmour.com for less than $30.
