Perfect for summer

Perfect t-shirt for the summer period, very light and super breathable. It's not as tight as xc outfits and therefore I find it much more comfortable. Leaves excellent freedom of movement. It also has a back pocket on the right side, it's good for putting something light, because since it's not too tight, it bounces around a lot. At this price you can't find anything better, unfortunately only one color available but I couldn't help but buy another one to have the change

Resistant to rubbing

Our design team selected a woven fabric for the sleeves so that you can ride along the trails without worrying about branches and brambles.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!

In a nutshell

Gender: men'sType of sleeves: shortCut: standardNumber of pockets: 1Resistant to vegetationUV protection

Straight cut

This MTB jersey is both sporty and relaxed!Theo is wearing a size M, and is 1.85 m tall.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 secure pocket

For carefree riding, plan ahead and keep the essentials to hand:- On your right, a secure pocket (17 cm x 11 cm) with an easy-open zip (even with gloves on!) so you can access items you need while riding with only one hand, such as your tissues, tyre 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 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.
