Bring back L/XL
What is going on with the sizing of this product? I bought the most recent one online (size L) and it is so small it leaves massive dents in my forehead and gives me a headache! Previous size L was tight but not constricting. I have an XL and it is comfortable but so large I can tuck my ears in which is not a good look. The original came in a size called L/XL and it was perfect, bring back that size. I have wasted too much money on these caps lately.

Best hat ever!
I love these hats! I have 3! Khaki, green, and camo. They are lightweight, breathable, good fitting and look great! I wear a size 7 1/2 fitted baseball hat and the size L of these hats is a perfect fit!

Not for someone with a big head, even XL
XL hat designed by a person with a M head. Sadly, I had to return the hat due to it being too small. Normally OR hats fit me but not this one.

Grady All-Around Cap
My go-to hat for work, hiking, travelling, and walking around the city. Folds small in a pocket, durable and easy to wash.

Great for a Fat Head
I am a fat head and it's hard to find a XL size, these fit. Wish that they came in a brown or tan.

Great hat
I've had a few of these over the years. They fit well, dry fast, are light weight, and durable. My new puppy chewed my last one up, so no hesitation I ordered 2 more. Thanks OR!

A Versatile Hat
- Familiarity:
- I've used it several times
- Size Bought:
- Medium
This hat is great in all kinds of weather, from hot sun to chilly fall days. It doesn't really provide much cold weather protection, but can work well to keep precipitation off when layered under a jacket hood. It also packs down nicely and can fit into a large jacket packet. It works well as a casual hat too, perfect style for grabbing a beer with friends or leading a revolution in a small country.

Nice lid
I really shouldn't recommend this hat to anybody else because I love it so much. I think everyone would probably start wearing it.

Almost perfect
This hat is very light weight and comfortable and folds up easily and is very functional. It does not breat at all though. If there were a breathable option I would give it 5 stars.
