Mountain tracking hat

Good fit with strapped pull tight. Prevented it from flying off even with strong winds at Mt Fuji. Provided good shade from the Sun.

Hello Y S,

Thank you for your review.

Glad to know that this hat served you well.

This hat can protect you from downpour for up to 2 hours. Also it can protect you from the harmful UV rays. Perforations at the top allow air circulation so you wont feel warm either.

Hope to hear from you again :)

substandard quality and feature

this hat does well in protecting me from the sun. however the water proof quality is not up to standard. as a coach and hiker, i own many hats to protect me from the sun and this is one of the worse i have by far. the rim is flimsy, it flips up with just a moderate gust of wind. the inner lining which is suppose to be around your forehead always goes out of position. once i was coaching and it began to rain, part of the hat absorbed the water and it is not totally waterproof.

Additional Product Information


Main fabric

  • 80% Polyester cationic
  • 20% Polyurethane

Inner fabric

  • 100% Polyester cationic


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 rating) but we also test the waterproof qualities of the finished product in an environmental chamber with reproduces different levels of precipitation. This hat will protect you from a 5" 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?

Ripstop 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.
