Hello Pradeep,

Thank you for taking the time to give us your review. Apologies for the bad experience with the jersey. I line on the jersey is a design element and is tilted across the chest. I request you to explain the same at the store and we will be happy to exchange the jersey for a new one.

Camiseta ciclismo

Talla pequeña, sobre todo en la axila y el pecho. Suelo usar M y me compre una L y es muy ajusada. La tela es muy muy gruesa porque lo que no extira y hace calor con ella en verano.

Buenas prenda

El bolsillo es un poco pequso, con un poco más de espacio en dicho bolsillo le daría un 10

Additional Product Information


Main fabric

  • 100% Polyester cationic

  • 9% Spandex
  • 91% Polyester cationic

Why pockets?

For carefree riding, plan ahead and keep the essentials to hand: - On your left, there's a pocket with an elasticated flap for carrying all of your personal belongings (bank card, cash, keys, etc.). - On your right, a secure pocket with an easy-to-open zipper (even with gloves on!) so you can access things you need while riding with one hand, such as your phone, tissues, etc.

The cut

This jersey is both sporty and casual with a V-neck and heathered effect. 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.

Resistant to brush?

To allow you to ride along the trails without worrying about branches and leaves, our design team selected a fabric with a tight knit. 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!

Tips from our team

When learning to mountain bike, remember to wear a helmet, 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.
