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!"

The cap looks and feels great and solid, a relief to wear this. As it had to come from the other side of the world - really down under for me in Europe, i was surprised to get the first notification in 7 days. Great stuff!

This is my second chiller cap. Even though it is one size I find the fit excellent, it is my go to cap in my MGB as it doesn’t blow off. The soaking to cool down is just wonderful.
