Technical Information

Our design team selected a fabric with a tight weave to allow you to ride along the trails without worrying about branches and leaves. The result? A real mountain biking jersey that resists both vegetation and rubbing from the straps of your hydration backpack. Plus, the material is designed to offer good ventilation!
For carefree riding, plan ahead and keep the essentials to hand: A secure pocket on the rear with an easy-access zip (even when wearing gloves!) to access useful items with one hand on your rides: tyre lever, tissues, etc. The jersey fabric is very stretchy, so we recommend only putting light objects in this pocket. Pocket dimensions: Length = 16 cm, width: 11 cm.
The cut
This jersey is both sporty and casual thanks to its motorbiking-inspired neckline and regular fit. Most of all, it's a real mountain biking jersey! 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.
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 chaffing. 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.
