Black Diamond StormLine Stretch Full Zip Rain Pants is a product that will meet the expectations of anyone who is going on a longer mountain hike and is looking for a model that provides protection from the rain. This is made possible by a special fabric that uses BD.dry™ technology, which ensures the pants are waterproof up to 10,000 mm water column. The technology also provides a fabric breathability of 10000 g/m2/24 hours. Model made using zippers with DWR water repellent treatment. The membrane has a two-and-a-half-layer laminate, which means that instead of a lining, a special protective layer is used to protect it from the inside. Model made with bluesign® certification. The trouser material is slightly elasticated to ensure a proper fit. The model has zippers on the sides to make it easier to put on without having to take off your crampons or shoes. The legs at the bottom have snaps and can be adjusted with the drawstrings. For larger pants, they have a seat with a special insert and properly sculpted knees. When you are not using this model, you can pack it in the back pocket. The model has a regular fit.
