Product Customer Reviews

It feels nice, it fits well, but to call the pocket a phone pocket is rubbish as it doesn’t fit my phone, which was the main reason for buying the top really. I guess the struggle to find female activewear with useable zipped pockets continues…
Very warm and confortable
Perfect addition for you mountain bike attire.
Very nice patent degsiner

Good and light material. Iron free which is good. Cooling to wear on hot and humid weather. Loose fit on me which allows movement.

Super
Fajn materiál, příjemný
Perfektní materiál
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.

Additional Product Information
Composition
Main fabric
- 100% Polyester cationic
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
Product made from 100% recycled polyester from plastic bottles. In this way, we are able to reduce our use of petroleum-based resources while retaining the breathability that you need from your mountain biking clothes.
