Good for waterproof, but consider other options...

I didn’t feel that these worked. I think the idea is great, but delivery is poor. These take a while to put in, and to remove, and when hiking non-stop adjusting to changing weather conditions, it takes 5 minutes or so to get changed, cutting the pace of the hiking. And then if weather changes, it takes again some time more to take them off and store them. So, if I am to use them as the only trousers, they might do the job, but they are not perfect, as they have no pockets or anything. And walking long distances with them slows the hiking. I often used them on top of trousers. It didn’t heat up a lot, but it made me look a lot bulky, like a was part of a rescue team. I did feel like they slowed me, as these do not seem like they were made for long distance hiking. I am not impressed with these trousers. Tissue needs to be more flexible, more adjustable to legs. The zippers need to be less stiff and more practical. Or more practical if they are to be used as main trousers (say with long john’s underneath, instead of another pair of trousers). My hiking partner used a pair of KALENJI MEN'S TRAIL RUNNING WATERPROOF PANTS – BLACK, and I did feel that those fitted him better than the ones I was using. Also, seemed more practical. After my experience, maybe using QUECHUA Techwool 190 Men’s Wool Trousers – Black + the trail running waterproof pants do the job just as well, and if I really want to make it super protected, I can always add on gaiters. This would be less expensive, and maybe a more practical solution, allowing me to keep a more constant and quick pace during the hiking.

Super pantalon

Adepte de treek et de rando reguliere. Je l'ai tester hier sous une forte pluie avec les chaussures pleines de boue, il est super facile à enfiler , c'est juste génial bravo aux concepteurs de ce produit. Le prix est élevé mais les matériaux utilisés sont de qualités. Donc il mérite ses 5 étoiles sans problème

Super confort

Pantalon très confortable et bien fini. L'étanchéité est tout à fait correcte et le fait de pouvoir l'ouvrir sur toute sa longueur permet d'aérer quand il ne pleut plus sans avoir besoin de l'enlever. Petit crochet bien pratique pour attacher sur les lacets sur le devant de la chaussurem. Plus besoin de guêtres. J'en achète un deuxième avant de ne plus le trouver ....

Sur pantalon très bon produit

Facile à enfiler grâce à la fermeture éclair complète le long des jambes. Solide, imperméable et respirant.

Additional Product Information


Main fabric

  • 100% Polyamide

Outer fabric

  • 100% Polyester cationic


  • 100% Polyamide

Hybrid construction

Combination of a durable and protective fabric (5.2 oz/m2; 70 Denier) on areas to be protected from rubbing (knees, lower leg, buttocks) and a light and breathable fabric (3.8 oz/m2; 20 Denier) elsewhere.

Side zippers

Using a waterproof zipper with a double slider lets you both regulate your body temperature and easily put on the overpants without having to remove your boots. Press-studs at the waist and ankles.


Bottom of pant leg has an elastic strip with silicone inside to improve grip on the boot. Lower leg hook to attach to the laces of the boot to prevent the overpants from riding up while walking.

Water-resistance of the fabric

The resistance of a fabric to water pressure is expressed in terms of the height in mm of a water column that can be supported by the fabric (test based on the ISO 811 standard). The higher the pressure, the more waterproof the fabric. Here are the waterproof values of the Trek 500 overpants: 25,000 mm before washing for the lightest fabric (11,000 mm after 5 washes) 20,000 mm before washing for the strongest fabric (17,000 mm after 5 washes)

Water-resistance of the overpants

The water-resistance of the overpants was tested under rainfall of 119 gallons of water/m²/hour for 4 hours. This test reproduces the conditions of a thunderstorm in the mountains.

Breathability of the fabric

To find out whether a fabric is breathable, we test its evaporative resistance or RET (based on the ISO 11092 standard). The lower the fabric's resistance, the more the water vapor 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 Here are the breathability values ​​of the Trek 700 overpants: RET < 8 for the lightest fabric RET < 12 for the most resistant fabric

How to restore water-repellent properties?

The water-repellent property of a fabric is its capacity to make water run off its surface without absorbing it. This prevents the fabric 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. In order to reactivate it, follow the guide:
