These shorts are designed to be durable and water repellent on mountain bike rides of over 3 hours. These women's MTB shorts are breathable, stretchy, water-repellent and resistant to vegetation. 2 secure pockets to protect your phone and keys. Very comfy waistband. Undershorts sold separately.

Technical Information


For carefree riding, plan ahead and keep the essentials to hand:
- one secure, waterproof pocket under the thigh on the right that's easy to access, even when wearing full-finger gloves, for holding your smartphone.
- a second secure, waterproof pocket on the back for your keys and a credit card.
Each pocket has an icon on it to help you get everything ready.


Our Rockrider clothing design team selected a fabric that withstands snags from vegetation and friction from your saddle.
The length of the shorts protects your legs from scratches (branches, brambles, etc.) on singletracks and also makes them compatible with mountain biking knee pads.


These shorts are intended to be worn in warm weather with the ST 900 undershorts, which are padded for comfort.
The fabric has a water-repellent treatment to protect from dirt all year round.
You can wear them with tights with a pad in cool or cold weather to protect you from dirt and drizzle. It's really handy being able to take your dirty shorts off before getting into your car!
Finally, the perforations at the crotch aid moisture management.


Delphine, our product manager, recommends shorts that cover the legs to protect from scratches on singletracks, along with padded undershorts for extra comfort. A breathable jersey that withstands snagging. Pockets for easy access to your bars and tissues, and secure, waterproof pockets for your smartphone and keys. Compatible with a hydration backpack! A helmet, glasses, full-finger gloves and knee pads are all the other things you need to be fully kitted out.


Through our test missions and user feedback, we noticed that mountain bikers took their gloves off frequently, before, during and after their rides.
Knowing where to put your gloves is always a problem, so we decided to add a press-stud to all of our gloves so they can be easily paired.
A loop has then been added to the shorts so you can attach them easily and leave your hands free to steer your bike... or take some photos!
