All you need, in your pocket!
To have everything you need when you head out for a ride, these shorts have clever pockets: - At the back there's a zip-up pocket for things like keys, credit cards, etc. - There's a zip-up waterproof pocket on the back of the thigh that's easy to access (even with one hand) and positioned to protect your phone from falls. - There are two places along your thigh for storing cereal bars: simply push down to get them out.
Keep your gloves to hand!
When mountain biking, gloves are often the last thing you put on and the first thing you take off. These shorts have a buckle on the waist so you can keep hold of your gloves without having to rummage around in your pockets. You can snap your ST 100 and ST 500 gloves on them using the press stud to keep them handy at all times.
