Adult Kelly green OTTO brand 5 panel mid-profile trucker hat with a leather mallard patch. Also available in Brown (also mid-profile) or olive green (high profile).
 
If you don't know the difference between mid and high-profile, don't worry- neither did we! The mid-profile is basically a little shorter, and the high-profile a little taller. The majority of our hats are high-profile but the dudes sometimes prefer mid-profile and we felt like this single patch was a little better on the mid profile ;) And now ya know!
