Product manager Delphine has a few tips for you:
"For mountain bike rides, choose a hydration backpack. It's an ideal solution to stay hydrated without stopping. With both hands on the handlebars, you can more easily get through challenging areas. And don't forget to wear a helmet and long gloves for safety. To prevent scratching your legs, cropped tights are a good compromise. One last accessory can come in handy: puncture repair spray."
