Product Customer Reviews

The longer tail works well in spring temperatures
Cheap as chips, won't last for ever but for an hour or two trailing and sessions...Great.
Je to super cyklistické triko. Jsem s ním nadmíru spokojený. Určitě bych si jej pořídil i další být v jiných barevných kombinacích.
Sehr gut:)
perfekt für den Sommer. preislich unschlagbar! gerne wieder!
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.
Très bien
Parfait léger pratique avec sa petite poche
rien à dire de plus
Habit très aéré quand on n'a pas le sac à dos avec
Top très léger
Très confortable et agréable.
Ras

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.

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.
