Frottements entre les cuisses

Je teste toute la gamme Mérinos et le boxer Mérinos trek 500 est une mauvaise surprise. Je l'ai utilisé pour des randonnées avec des pantalons de randonnées et j'ai tout de suite senti une irritation désagréable entre les cuisses provoquée par un frottement avec les coutures. Je l'ai aussi utilisé avec des pantalons de courses à pied plus ajustés et moulant et là le frottement disparaît puisque le pantalon colle le boxer au corps et évite ainsi le frottement des coutures entre les cuisses. Sinon le tissu est confortable.

Bonjour monsieur,


Et merci pour votre avis sur notre produit.

Nous sommes sincèrement navrés qu'il ne vous apporte pas satisfaction.


Nous vous invitons donc à le ramener dans votre magasin Decathlon le plus proche afin de vous le faire échanger ou rembourser dès que cela sera possible.


D'ici là, prenez soin de vous.




Directeur Forclaz "Durable Trekking Gear"

Additional Product Information


Main fabric

  • 4% Spandex
  • 10% Polyamide
  • 86% Wool

Sizing and fit

These boxers have an adjusted cut to facilitate the transfer of moisture to the outside of the fabric.

Origin of the wool

We only use wool from Merino sheep bred on farms in South Africa that do not practice mulesing. We decided to build a partnership with a group of breeders (Konsortium Merino) to guarantee respect for animal welfare and the environment. So we have full traceability, which allows us to guarantee the origin of the wool. More information:


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.



Product testing

These boxers have been tested and validated in the field in real-life conditions. They were worn for 5 weeks in spring 2019 by several people who went backpacking in the Canary Islands for 2 weeks, followed by 3 weeks on the GR10 route in the Pyrenees.
