Great product
Did not act as a thermal
They would be nice, but the seams are so scratchy that they are not suitable. Massacre. Unfortunately refund.
I've had the pants for a good month now, and I've used them almost every day under my jogging pants for walking the dog for 1-3 hours, and I haven't washed them very often so far (
good
Comfortable and warm. Very happy
I use it to go to work on a motorbike every day in very cold weather (4 to 10 degrees) and it's definitely better and above all much cheaper than technical motorcycle clothing (Daenese for example). Ultra thin and light (I don't feel it on the skin) it stays super warm even with 100 km/h of Mistral. I'm going to buy one for hiking, that's for sure. Combined with the sweater from the same series, I'm super warm 🔥. Big plus, it's super breathable, so I don't sweat in it. Warm and dry!
Excellent and not only for "sport"
The tights allow for smooth movement because they don't stick to your pants
Warm, odorless tights that don't make you sweat particularly. Used mainly in the evening once we arrived at the camp or bivouac and a few nights in the sleeping bag when the temperature dropped considerably. I had a great time, I recommend it. We all know the advantages of merino products
Comfortable
Durable
easy to wear
I originally bought these tights for my winter motorcycle trips. Very comfortable, keeps you warm and wicks away perspiration well. I also used it on hikes, treks, and ski trips. No friction when walking. Excellent value for money, I highly recommend!
182 cm 92 kilos fit. Naturally slimmer legs. Drove upper part in XL and L on lower part. Fits perfectly and is comfortable. No scratches or the like. Great that you can trust size recommendations. Will be buying more in the future.

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.
