Measuring Your Head Size
- To determine your hat size follow these 3 simple steps:
Measure the circumference around your head - approximately 12mm (1/2”) above the ears - Keep the dressmaker tape level and firm, across the temple and above the eyebrow ridges.
- Check the size chart given above.
NOTE: For in-between measurements use the next size up.
For A Perfect Fit.
If you’re on the border and worried that the next size up will be too loose, just add our custom Hat Filler’s under the front and rear elastic sweatband. They will be out of sight while you tailor your Chiller to be the perfect fit!

"Thank you I love my hat! Ordered my pearl Bushie Plus just before travelling to Sicily and with the swift delivery I got it in time for departure. I’m so satisfied with my hat that I will order also another modell when home again. Thank you for proving how online shopping really should be. I will recommend to anybody to go through with a purchase from Aussi Chiller."

"The best hat I’ve ever owned! I travel a lot and was looking for a versatile packable hat for warmer weather. I explored the Aussie Chiller site and ordered the perforated Bushie based on the reviews. I’m so happy I did. I live in the northeast US and recently traveled to Key West Florida. The Bushie came out of my suitcase unscathed. Just popped it back in shape. I wore it all the time from the beach, pool, soaked it and it kept me cool in very warm weather. I’m a musician and wore it to perform. I received so many compliments. I’m going to order a solid Bushie plus for the cooler months. Thank you Aussie Chiller for a wonderful well made hat!"

What an oustanding cap! It is not only super comfortable right out of the box and has a nicely rigid bill, it's also very breathable and, of course, soakable! When flying in a plane with a plexiglass canopy, it gets remarkably warm in the cockpit in the summer months. This cap proved to be extremely comfortable and breathable while keeping the sun off my eyes. LOVE my Aussie Chiller cap and highly recommend it to others!

I bought this for my husband who’s a keen angler in the UK. It’s a great fit, lightweight & perfect for dipping in the river to cool off. Really pleased with the quality of the product & customer service.

I haven’t bought a hat in years that wasn’t a Richardson 112. I’m picky about hats and pretty much refuse to wear anything else.
I ordered my wife a Bushie and bought this one on a whim, fully expecting to try it on, instantly hate it, and chuck it in the back of the closet where it would be forgotten forever.
Well… shit.
This thing fits like it was made for my head, and that’s saying something. I’ve been accused of having a head large enough to possess its own gravitational pull.
The sweatband is soft, and the hat stretches where it needs to without stretching where it shouldn’t. It’s comfortable as hell right out of the box.
Full disclosure: it just showed up today, so I haven’t actually worn it out of the house yet. Tomorrow it gets its first real test on a good ol’ Missouri 100-degree day.
Are these hats cheap ? NO But cool shit ain’t cheap and cheap shit ain’t cool
So far, though, I’m impressed. Apparently my Richardson 112s finally have some competition.
