An ultra-lightweight wide-brimmed hat made of nylon material that can be used in all seasons. The inside is made of mesh material, making it breathable and preventing stuffiness. Even if it gets dirty from sweat, it can be hand-washed, so you can keep it clean at all times. It comes with a detachable chin strap, so you don't have to worry about it blowing away on windy days or when cycling. Also, the strap is made of retroreflective material, so it reflects light from oncoming cars, ensuring safety on night roads. It can be folded small, making it easy to carry around, which is a great feature. It is perfect not only for camping and BBQs, but also for outdoor events such as festivals.
