Beautiful, well made, extremely light weight. I have a very small head and have difficulty finding hats that fit. This fits with lots of room to cinch down. As a right hander, it’s a little difficult to adjust as the cinch is on the left. As others noted, the brim is a little too short and narrow to really provide shade, but I always wear sunglasses anyway. I run in 80+ degree heat and this is perfect.

Great fit, doesn't blow off while running. Super light and breathable for hot humid Summer days.

Awesome Hat

Love the hat! Love the colors, fit, quality and it weighs nothing. The adjustment in the back is so easy as well.

Wear a weightless cap on that beautiful head!

Only choosing or gifting these hats from now on.

Those who have longer hair - doesn’t create a crease/dent in your hair either! Light, so no headaches!

Super light. Great running cap! Stops sweat. Brim is too short.

Awesome running cap!!

The only thing I would love to see is a longer brim to block the sun. It's too short.

Great bungee system, tight but comfortable. Cinched down enough that it didn't blow off during 20mph winds while running!

Perfect for travel

Love this hat, I brought it to Disney with me for when the sun got too intense, it packed in my Lululemon fanny pack perfectly and still had room for chapstick, creditcards, sunglass case, and travel sunscreen. I stuffed it way in the bottom and it always came out flawless, brim always perfect. I also love that the brim flips up and stays up, great for when going in and out of places and on rides where you don't want your vision impeded by a brim, but you don't need to take the hat off completely. Did not mess with sunglasses around ears. I have a big noggin and it is very adjustable. Can't wait to wear it running, I feel it will be perfect.

Amazing hat for all activities

Stylish, lightweight, pocketable hat. Perfect for sunny and hotter days and doesn’t warm up the noggin too much when I’m active. I receive a lot of compliments too!
