Technical information

What is the mechanical anti-mosquito solution used for the TROPIC 900 hat?

the extra tight woven component used for the product acts as a mechanical barrier that limits mosquito bites when it is not pulled tight.
We chose a mechanical solution with permethrin-based impregnation (biocidal product) which is less toxic

How effective is the mosquito net on the TROPIC 900 hat?

The World Heath Organisation recommends at least 25 holes per cm² to stop mosquitoes effectively.
With 40 holes per sqcm, the mosquito net used on this hat won't let any through.
This net is untreated.

How do I fold my TROPIC 900 hat?

Just make an "eight" with the edge of your hat and then fold it in half.
And... there you go! Place it in its specially-designed bag.
This tip will enable you to carry your hat in your rucksack or suitcase without damaging it.

How do you protect yourself in the areas that are prone to mosquitoes?

If you are visiting an area with a high level of mosquitoes, we recommend you also use anti-mosquito spray, essential oil-based with lemon eucalyptus or even icaridin.
In fact, in some countries mosquitoes can be carriers of serious diseases such as chikungunya, dengue fever and even malaria.
