Muy buen Maillot!!!!!

El maillot se ajusta muy bien, además los dos bolsillos traseros con cremallera son un acierto, lástima no poder encontrar disponibilidad del maillot en color rojo

Maillot super comodo, elastico y resistente. Tuve una caida con un enganchon por rama y el maillot intacto. Es disañado 100% pensado en mis necesidades.

Cadeau de l'équipe cycle Decathlon ALLEUR

Petit cadeau reçu de l'équipe cycle Decathlon Alleur. Testé ce jour, sortie de 56km, 31km/h de moyenne et T° moy de 27°C. Le col dégagé procure une sensation de frais. Les manches collent bien au biceps, grâce à l'adhérence intérieur (style caoutchouc). Même chose à l'arrière, bas du maillot. La tirette un peu grosse, mais sans doute plus solide que dans certaines marques connues. À l'arrière, le dos est ventilé, ce qui fait que je ne suis pas rentré trempé comme à l'habitude. Les 3 poches arrières sont assez grandes que pour y mettre les nouveaux smartphone assez grands (Samsung S8 y rentre facilement). Les 2 tirettes latérales sont pratiques pour y mettre clés ou argent, ainsi certain de ne rien perdre. Bref un bon maillot. Content de mon cadeau.

Le bon maillot

Excellent produit qui correspond au but recherché: éviter la transpiration et un port agréable. Certes il y a le prix=

A word from the team

Entirely designed and developed, from initial sketch to final model, in France at the B'Twin Village (Lille), this JERSEY is the work of an expert team of passionate cross-country mountain bikers. The Rockrider team designed and tested the XC LIGHT JERSEY with their user testers and technical partner, Milton Ramos. The Cross Country clothing team is proud to present the XC LIGHT JERSEY, which has been 100% designed for XC use

Pocket system

We observed the most demanding users in the world and came up with a new way of constructing our XC jerseys. Go ride cross country with your smartphone and keys in a safe place 2 secure pockets with easy access to your smartphone and keys 1 side easy-access trash pocket to preserve our outdoor playground


When riding fairly technical sections, it's not always easy to undo your jersey and cool down. We chose this zipper because it's quick and easy to open one-handed, so you can always keep one hand on the handlebar.

A rating to compare our products' environmental impact
