Excellent inner wear

Excellent inner warm wear

Not very warm

I bought these for a 10 day trip to Ladakh in October. The decathlon sales person recommended these over the basic Wedge tights and said that these would be warmer as they are made of Merino. Honestly, I didn't feel much warmth with these under the Trek 900 pants. The Wedge base layer is much warmer in my opinion. Also, the elastic band around the waist is horrible with a size S running between 87-92 cms (about 34 to 36 inches). The tights keep running down if not worn with another layer on top to secure them. I don't what size slimmer guys like me are going to get.

Hello Mr. AR
Thank you for taking out time to give your valuable feedback . We are extremely sorry for the bad experience you had. 
We generally recommend Merino wool for long trips like yours because their major benefit is that they are anti bacterial because of the type of wool you can use them for multiple days ,even upto seven days while Backpacking  or Trekking and the product won't develop  any bad odour and also they are warm.
However we really appreciate you writing us about the elastic fault and expressing your dissatisfiction, Please reach out to your nearest Decathlon store and get your product exchanged or refunded.
I hope the information was helpful, kindly write back to me in case of any further queries.

Para protegerse del frío No cumple

En mi caso me las compré para complementar la indumentaria necesaria para esta época del año debido a que me desplazo en moto y paso frío con ellas puestas, en mi opinión no valen lo que cuestan ni de coña, ahí lo dejo.

Je vous remercie d'avoir pris le temps de nous faire part de votre expérience avec le collant Trek 500 mérinos.

Je suis désolé de lire que vous n'êtes pas pleinement satisfait de votre achat et vous prie de nous en excuser.

Vous savez sans doute que nous utilisons de la laine mérinos très fine (18,5 microns) connu pour sa douceur. En outre, nous conseillons de laver une ou deux fois avant la 1ère utilisation nos produits en laine mérinos afin d'en améliorer la douceur au contact de la peau.

L'immense majorité des utilisateurs sont d'ailleurs satisfait par le confort du mérinos.

Cela étant, comme vous l'écrivez, certaines personnes sont plus sensibles, et peuvent ressentir des démangeaisons au porter de la laine.

C'est pour cette raison que je vous invite à vous rendre dans un magasin Decathlon pour procéder à un échange ou un remboursement.

Origin of the wool

We only use wool from Merino sheep bred on farms in South Africa that do not practice mulesing. Merino wool is a renewable material; it grows back after each shearing. We use very fine Merino wool for this base layer (18.5 microns): it is very soft and doesn't itch. More information:


A new yarn structure in which a polyamide yarn forms a thin sheath that protects the merino wool fibers against friction and cuts



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). You can expect wind, rain, a bit of snow, a bivouac... and a lot of fun! We were able to make the final modifications and validate it for use in mountain backpacking.
