Value for money. The compartment is handy.

Je to super cyklistické triko. Jsem s ním nadmíru spokojený. Určitě bych si jej pořídil i další být v jiných barevných kombinacích.

Passt und ist richtig gut fürs Geld

Ich nutze die Shirts zum laufen wegen der Taschen für's Handy, die sind dafür aber nicht hundertprozentig dafür geeignet weil der Stoff so leicht ist. Auf jedem Fall ist das Shirt gut zu tragen.

Leider keine wirkliche Tasche

Sitzt schön luftig, schaut gut aus, lässt sich in die eigene Tasche einpacken, außer dieser fehlt es allerdings an den fahrradtrikottypischen Taschen, daher einen Stern Abzug.

Un primer precio que cumple de sobra

Para el precio que tiene no voy a poner ninguna pega. No creo que nadie se compre esta camiseta pensando que va a ser hiper-mega-super-resistente... porque por precio ya se sabe que no, pero es fresca para los días de verano, de momento tiene algún enganchón con zarzas y no se ha hecho ningún desperfecto notable más allá de la marca en el punto donde se engancha la rama y es muy cómoda. Seguramente me compre más para tener recambio.

Es una camisetilla fina

La considero una camisetilla fina, como de running. Eso sí, es muy fresca. Tiene las mangas más reforzadas, aún así muy fino. La espalda no reforzada, como se indica. Porque cuesta 11 euros, sí no la hubiera devuelto

Le tissu n'est pas agréable

On a l'impression de porter un vieux vêtement tout chiffonné

Bonjour Khalid,

Merci pour votre retour. Si la sensation du maillot n'est pas agréable pour vous, nous vous conseillons de monter un peu en gamme pour votre prochain achat. Le tissu sera dès lors, plus agréable à porter.

Bien à vous,



Facile et agréable à porter

Additional Product Information


Main fabric

  • 100% Polyester cationic

Sleeve fabric

  • 14% Spandex
  • 86% Polyester cationic

  • 9% Spandex
  • 91% Polyester cationic

Resistant to rubbing

Our design team selected a fabric with a tight weave so you can ride the trails without worrying about branches and leaves. The result? A real mountain biking jersey that withstands snags when riding through brush, as well as friction from the straps on your hydration backpack. Plus, the material is designed to offer good ventilation!

Straight cut

This jersey is sporty, relaxed, and fully designed for mountain biking! The cut and seams were designed to prevent friction and to keep you as comfortable as possible while in a riding position. For example, the jersey is long enough in the back to keep your entire back covered, even when leaning over your handlebar.

1 secured pocket

For carefree riding, plan ahead and keep the essentials at hand: - On your right, a secure pocket (17 cm x 11 cm) with an easy-open zipper (even with gloves on!) so you can access items you need while riding with only one hand, such as your tissues, tire levers, etc. - The jersey material is very extensible; we recommend using it for lightweight items. - You can pack the jersey down into this pocket, for easy transportation and storage.

Packed size

Length: 15 cm Width: 11 cm Height: 5 cm

Product care

Advice from the team

Think about wearing a helmet and gloves when you start mountain biking: not just for falls, but also to protect yourself from low branches! For comfort, wear a pair of shorts with a pad to prevent chafing. A water bottle or hydration backpack will keep you hydrated. And finally, puncture repair spray so you can finish your ride without having to fiddle with repair tools.
