These hats are made from two kinds of Coated EVA. A softer material is used around the head and a more structured material is used for the brim. Coated EVA is commonly found in sneakers, yoga mats, and knee/helmet pads. It feels very similar to a soft, cushiony memory foam and is very comfortable.

No. This material does not absorb and transmit heat the way plastic and leather do. Coated EVA is an insulating material which means that the hat may get warm on top but stays cool underneath where it makes contact with the head. Even the black hats stay comfortable!

While the hat can NOT be rolled up, the material is very soft and flexible. We recommend packing around the hat. If the hat does get bent or crushed during travel, it will crease initially but the creasing will fade and become almost invisible and the hat will retain its shape and be totally usable.

Cleaning is easy with mild soap and water... wipe dry to avoid water spots. Alternatively, you can use Windex with Vinegar or alcohol wipes to spot clean. We recommend removing chlorine and sunscreen stains as soon as possible.

One premium "NoSweatCo" band is inserted in every hat to absorb perspiration. These last for months and months of daily use and can be reordered on Amazon or on the company's website. If the band gets wet in the pool, it will simply dry and be usable again. Use Goo Gone to remove any adhesive that sticks to the hat when changing the band.

All hats have an elasticated ribbon closure that allows the hat to stretch to fit. For small heads simply overlap the holes in the back and tie the rope through them. This is for heads measuring 21 inches. The hat can fit heads measuring from 21 inches to 25 inches.

YES! These hats are 100% waterproof and will float. They can also be used in the rain. Tropical destinations where the weather alternates between rain and sun frequently throughout the day is ideal for these hats because they are not affected by water at all.

Our customers love the open top for the following reasons: more adjustable fit, more airflow, doesn't flatten their hair (i.e. no "hat hair"), and they can put their hair up in a pony tail.

We recommend hanging the hat to protect the shape and prevent crushing.

Most likely not because this may be the lightest hat on the market at only 1.2 ounces. Combined with the cushiony, adjustable fit and heat-resistance means headache-free comfort for hours and hours.

No, this material is UV resistant to fading and deterioration. Your hat will look new for years.

For more of a "hat look" that hides the top of your hair, we suggest the Tall 3 inch height. Otherwise, the lower 2.5 inch visor is very popular.

The bands are made of thin but durable decorative fibers like hemp and bamboo. We attached the fibers to the hat with a sealing material and then use acrylic paint to create an elegant border.
