This is the DoD JOE B HAT. I was preparing all sorts of camping gear and forgot a hat. When I arrived at the campsite, the sun was surprisingly strong. The JOE B HAT is a convenient, always-ready hat for such situations. It can be stored compactly by putting it in the included case. With the carabiner, it won't get in the way even if you attach it to your backpack or belt loop. Wire is inserted into the brim, and the hat pops open when you take it out of the case. The brim is designed to be wide, protecting your face from sunburn. The fabric is also UV-cut treated. It's a reversible design that can be used to match your fashion and preferences. It's also water-repellent to handle light rain. It has a chin strap and adjuster to prevent the hat from blowing away in the wind. It's finished like a tulip hat, so it fits a wide range of head sizes. 〇 Size Product body (approx.) Diameter 33 x H15cm Head circumference (approx.) 58cm Storage size (approx.)
