Description

“Lightweight and breathable, this sun hat features an interior sweatband for the hottest days. Plus, it's packable, and the brim can be worn up or down.” 

— Oprah Daily 

Carefree and casual, just like its namesake island! When the temps rise, you’ll reach for the Kauai for that cooling bit of shade and breathability. The upturned kettle brim puts a gleam in your eye, and the matching hatband adjusts to size. The Kauai compresses down to squeeze into even the most overpacked luggage, right next to your souvenirs.

This is the perfect goes-with-everything summer hat! I add different bands and scarves to add color.

Love this hat. It is not hot to wear and It is not heavy on my head. Not too fancy just right for casual

As always, Sunday Afternoon comes through. The Kauai hat is probably the fifth I’ve ordered over the years and each one has been better than expected. Great quality, well packed and delivered amazingly fast!

Beautiful hat. A little too big but the small would be too small. Great quality.

Wouldn’t be caught in garden without it

I have owned this hat for many years.  I was an organic lavender farmer and now just a gardener and I wouldn’t be caught in the garden without it !

DNTNDIVA In her Sunday KAUAI HAT

I bought this hat in both colors three times. I absolutely love it and I get so many compliments on it. It really shakes my face and I live in Arizona so I pretty much can wear it year-round. Awesome hat thank you Sunday for making this hat I like to think it’s just for me

So disappointed.

The hat is EXACTLY what I want and need. But way too big. I measured very accurately but the brim is so big. Bigger than their measurements said. Retuned it minus $5
