Product Customer Reviews
I am a tall woman so got these for decent leg length, to go under my shell type overalls for snowboarding. I just got back from France and there were some really cold days, but these were great paired with the black Wedze ski socks. fully recommend
Men's merino wool mountain trekking underwear tights/leggings purchased as a base layer for mountain biking or gravel riding in winter.
They are suitable both for winter and other seasons, they are light and have good thermoregulation.
Absolutely great. Super comfortable, size is just right, so you won't get complexes. For hiking in the mountains in winter, for walking around the house like an old man in long johns, for sleeping when it's cold.
Very good value for money
Comfortable to wear
very good product, warm and light
Excellent, I don't regret my purchase.
Only used for sleeping in humid weather between 5 and 10°C. Perfect.
Cool stuff
The elastic waistband is a little high and a little tight. Otherwise, it's very warm as underpants for cycling, and very warm as "pajamas" for camping when it's very cold.
Comfortable to wear
product used on the gr34
Article meets our expectations
Use only for sleeping in a sleeping bag, the product appears to be of good quality, we will see in the long term.

Product testing
In November 2018, 8 trekkers (4 men and 4 women) and part of the Forclaz design team, tested these tights for 4 days in the southern French Alps (Lus La Croix Haute). You can expect wind, rain, a bit of snow, a bivouac... and a lot of fun! We were then able to make the final modifications and validate it for mountain trekking use.
