Great all around and durable. Will last a long time.
Size: Large-X-Large, Color: Black/Anthracite/White
Great hat for being lightweight yet holding the sweat it needs to while also being cooling with the air vent holes. Perfect velcro that moves and does not collect junk in the wash. Durable and is long lasting. Have used for many months and wear a visor daily. It is my favorite.

Great lightweight & breathable visor for the outdoors
This visor is nice & light-weight. I love the style & the tiny holes in front for breathability! I’m a huge Nike fan & appreciate the sturdiness, softness & comfort. It has a soft velcro adjustment, so it doesn’t scratch the back of your head, which is a plus. Value for the money is a little high, but well worth it since it’s my go-to hat for playing tennis, running or walking. Highly recommend this to others.
