Opening direction of the hand pockets:

We deliberately positioned the fastening direction of the hand pockets downward. This means that the zipper slider will never bother you when you tighten the waistband of your backpack, and your belongings will remain secure in your pockets!


2 hand pockets that zip downward. 1 zipped left thigh pocket 1 right thigh pocket with flap and 1 internal smartphone compartment. Supplied with a belt.

Water repellency info:

These pants feature water-repellent areas (front of lower leg, backside) that prevent water from entering the fabric. Please note that this does not mean WATERPROOF. Water-repellent means that the pants don't get wet too quickly but they will not keep you dry under normal rainfall. You would have to add overpants for this. The water-repellent property can be reactivated: Follow the guide!
