I underestimated the cold while camping on my cycling trip through Belgium and Luxembourg last week. Quickly find a Decathlon and buy something for extra warmth. It was often humid with temperatures between 5 and 10 degrees, this base layer really helped keep my legs more comfortable. Worn a few times while cycling under my shorts and it was very pleasant in the cold morning. When the sun came out it quickly became way too hot. Good panic buy for extra warmth when you need it. I can't say anything about wear resistance yet.
Very pleasant to wear
good
Perfect
Helped keep me warm, perfect
Served me at the bivouac or at night in case of cold nights... very satisfied!
The quality ratio is good and the wool/polyamide material is not irritating. The other advantage compared to polyester is that this material does not retain odors and it works perfectly.
Comfortable and good pants. It's just the right size.

This range is a MUST have, that's why we come back to it! It does everything we expect to see more of. Used in Mountain Trekking and the cold streets of New York.

Additional Product Information
Composition
Main fabric: 86.0% Wool, 4.0% Elastane, 10.0% Polyamide ; Yoke: 98.0% Wool, 2.0% Polyamide
Sizing and fit
These tights have a close fit to help the transfer of moisture to the outside of the fabric.4% spandex added for comfort and freedom of movement.
How have we reinforced the durability of these merino wool tights?
Use of a BETA-SPUN yarn structure in which the polyamide threads coat the Merino wool fibers and protect them from rubbing and cuts without affecting their properties.
Odor control
Wool from Merino sheep naturally controls the spread of bacteria that cause bad odors. These Merino wool tights can therefore be wornseveral days in a row and means you can take less clothes when backpacking making for a lighter backpack!
Tip before use
For a softer feel, wash your tights before 1st use.
How do i wash my merino wool tights?
We recommend that you machine wash your Merino wool tights at 86°F on a normal cycle, preferably with liquid detergent. Dry flat and NEVER tumble dry unless you want it to shrink by 1 or 2 sizes!
Product testing
In November 2018, 8 backpackers (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). On the agenda, 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 use for backpacking.
