How to Choose the Perfect Oobi Hat Size (and Why They’re the Best Kids Sun Hats in Australia)

When it comes to sun safety for little ones, not all hats are created equal. At Oobi, hats aren’t just stylish, they’re carefully designed to protect, fit comfortably, and last through every adventure.

Whether you’re shopping for your baby’s very first sun hat or looking for a playful style for yourself, Oobi has you covered (literally!).

Why Are Oobi Hats the Best Kids’ Sun Hats in Australia?

Oobi hats are thoughtfully designed with both sun protection and comfort in mind:

• Superior UV Protection – Double-layered fabrics, denim linings, and wider-than-usual brims keep your little one shielded from harsh UV rays without blocking vision.

• Adjustable for Comfort – Most Oobi hat styles (except for reversible bucket hats)  include adjustable toggles and straps so you can find the perfect fit. Don’t like toggles? No problem, you can simply remove them by cutting it off and the hat will still fit beautifully.

• Smart Features – Our Chloe Hats include a ponytail hole, making them practical as well as stylish.

• Reversible – Some styles can be worn two ways and are reversible. While these don't include toggles, they have a deeper dome so they stay secure all day.

• Machine Washable – Oobi hats are made with easy-care fabrics. Just pop them in the wash after a day of adventure and they’re ready to go again.

• Family Sizes – From newborns to tweens, teens, and even mums, we have a wide range of sizes so everyone in the family can enjoy matching protection.

No wonder they’re loved by parents across Australia, our hats are fun, functional, and sun-smart.

How to Measure for the Perfect Fit

Every hat product page at Oobi includes exact measurements, but if you want to be extra precise:

1. Take a tape measure (or string and ruler).

2. Wrap it gently around the forehead at the spot where you want the hat to sit.

3. Use your measurement in centimetres to choose the right size.

4. If your child is between sizes, always size up for comfort and longer wear.

The Oobi Perfect Fit Guarantee

Still worried about sizing? Don’t be! Oobi offers a Perfect Fit Guarantee on your first order, meaning if you choose the wrong size, you can exchange it easily as long as tags are intact and the hat is unworn/unwashed.

With Oobi, sun protection doesn’t just mean safety. It means fun, comfort, colour, and style for the whole family.
