Product Customer Reviews

Perfect addition for you mountain bike attire.
SELESA DI PAKAI WALAUPUN CUACA PANAS
Na první pohled hezké tričko, které jsem bohužel nevyzkoušela. Velikost sedí, všechno je asi jak má být, ale není to kousek, který budu nosit často a ráda. Vlastně ho asi pošlu dál.
Špatně šité v pase moc odstává.
Příjemný a slušivý cyklistický dres.
vzdušné, lehké
Silnější cyklodres voného střihu, s malou kapsou na zip. V kapse byla díra (rozpáraná).

Within arm's reach!
For carefree riding, plan ahead and keep the essentials to hand: 1 secure pocket for your smartphone with an easy-to-use zipper (even when wearing gloves). Easy access with just one hand so you can enjoy your mountain bike ride to the max. A clever mountain biking jersey: the pocket is accessible even with a hydration pack on your back.
No more snags!
To hit the trails without worrying about branches and leaves, our ROCKRIDER clothing design team chose a special fabric that won't ladder if snagged on vegetation. The result? A real mountain biking jersey that withstands getting snagged on vegetation and friction from your hydration backpack. The fabric is also ventilated for better moisture management.
Our lab and field tests
The fabric on the ST 100 women's jersey has been tested in the lab for 2 essential criteria: - resistance to snagging on vegetation and friction from a backpack. - efficient perspiration wicking. These tests were backed up by field tests carried out by female mountain bikers to check that the jersey is exactly the right shape and size for women.
Our tip
Our product manager Delphine has a few tips for you: "As a beginner, there are a few mountain biking essentials you'll need: pants with a pad to keep you comfy in the saddle. For an even more comfortable ride, try using a gel saddle cover. As for your hands, don't wait until you fall to find out how important gloves are to mountain biking. Ready? And remember your helmet and water to keep you hydrated (in a bottle or hydration backpack)."
100% recycled product
