Lightweight & a nice style

We were considering buying the anti mosquito hat but when we went to see it in the shop, we decided to buy this instead as the brim of this hat is straighter, lightweight and looks nicer.

It really is waterproof for 2 hours as I found out first time I wore it! Rain just slid off! Even bought a second one.

Waterproof Hat

Not good when there is a lot of wind as the hat is easily deformed by the wind. Otherwise a great hat, easy to carry around and comfortable.

Good Rainhat

Bought it for fishing offshore in wet conditions. I experienced rain and lots of salt spray and it worked just fine. A bit stiffer brim would have been nice in the wind because the brim tends to either flip up or be pushed down over your eyes. I'll probably use it for hiking as well because its light and very crushable - easy to take along.

Hello Ian


Thank you for taking the time to write to us about your product experience. We truly appreciate your feedback.

Have a great day :)

Thanks & Regards,

Decathlon Brampton Team


Fits great. Lightweight. Super comfortable. I have a tendency to overheat. Especially when I wear hats. Was on the water in direct Sun and wind and had complete protection while never overheating. My daughter bought a “Tilley” hat from another vendor and didn’t share the same experience. She will be buying this hat now.

How does Decathlon measure waterproofing? At Decathlon, we don't just consider the intrinsic quality of the component (in this instance, a fabric with a 20,000 Schmerbers rating) but we also test the waterproof qualities of the finished product in an environmental chamber reproducing different precipitation levels. This hat will protect you from a 4.7" rain shower for 2 hours, or 60 L of water per hour and per square meter: quite a downpour!

What makes ripstop fabric more durable?

The ripstop fabric is a mesh-type fabric. The warp and weft design helps ensure durability and prevent potential tears.



Product testing

The entire design team was able to test this hat during frequent excursions in the Mont Blanc mountain range, where Forclaz – Decathlon's backpacking brand – has its offices.
