Hybrid structure

Combination of a durable and protective fabric (147g/m2; 70 Denier) on the areas to be protected from friction (shoulders, outside of the sleeves, bottom of the garment at the front and back) and a light and breathable fabric (109 g/sqm; 20 Denier) elsewhere.

Back 2 cm longer than the front to ensure maximum protection and to cover the second thermal layer underneath if necessary.


With Hood,

Completely adjustable hood height and depth.

Semi-rigid visor with integrated mesh headband to provide a high level of protection and support.

The high stand-up collar effectively protects the lower face.


2 hand pockets that remain accessible even when carrying a backpack and a YKK AquaGuard waterproof zip.

There is a mesh pocket for a mobile phone inside the right pocket to keep it safe and prevent it from falling out when you open your pocket.

Front zip

Features a waterproof YKK AquaGuard zip along the entire length with an inside flap providing protection from the wind. Folded underflap on the hem to make zip fastening easier.

Double slider lets you open the jacket from the bottom.

Soft fabric flap at the top of the collar to protect the chin.


Double tightening with an elastic cord and toggle at the hem.

Velcro-adjustable sleeves covering the wrist.

The wrist fob makes it easy to wear gloves with the jacket.

Water resistance of the fabric

The water resistance of a fabric, ensured by a coating or a membrane, is measured in Schmerber or mm of water (pressure exerted by a column of water). The higher this number, the more waterproof the fabric.

This jacket has two waterproof components (norm JIS L 1092):

- The main component is very waterproof. It is resistant to

20,000 mm of water (Schmerber rating) before washing- The secondary component is at thigh level and is resistant to 20,000 mm of water (Schmerber rating) before washing

Water resistance of the jacket

A jacket’s water resistance is not only determined by its components: The technique that is used to assemble the different parts is also an evaluation criterion.

Whether it is ironed or sewn and then made waterproof, the overall water resistance of your jacket is measured using a shower test developed by Decathlon, which simulates rainfall of different intensities.

So, the MT500 waterproof jacket protects you from a rainstorm in the mountains, that is 450 litres of water /m²/h for 4 hours.

Fabric breathability

To assess the breathability of the fabric, the evaporative resistance, RET (test based on the ISO 11092 standard), is measured. The lower the fabric's resistance, the more water vapour generated by physical activity evaporates, and the higher the fabric's breathability.

It is considered that if:

* RET < 9 = very breathable fabric

* 9 < RET < 12 = breathable fabric.

The breathability qualities of this jacket:

RET < 8 for the lightest fabric

RET < 12 for the most resistant fabric

Information about water-repellent properties and how to reactivate them.

How well the product leaves water on the surface.As a result, the garment does not soak up water and stays light.

This prevents your product from soaking up water, and keeps it lightweight and breathable.The fabric is made water-repellent by treating its outer surface, however this property may deteriorate with use.

The water-repellent properties can be reactivated by warming the jacket in a tumble dryer on a low heat for 10 min.

You can also use the FORCLAZ re-waterproofing spray (ref 855490)
