The Stormline Stretch Rain Pant is ready to keep you dry no matter what the weather throws at you. With its BD.dry™ waterproof/breathable/windproof solution which is engineered to shield you from volatile weather. They are very sleek and packable making them a great piece of clothing to bring with you anywhere. The Stormline Stretch Rain Pant is also very comfortable and durable thanks to their ultra-stretchy fabric, and with their gusseted seat and articulated knees, they will never hold you back. Lots of other waterproof trousers are not breathable but Black Diamond has added full-length side zippers on either leg to make it easier for you to regulate temperature and to put on over your layers. They also have an internal elastic waist with an internal drawcord to give you the fit you want, and a back right zip up pocket which they will stow into and then you can put them out of your way on your harness using the carabiner loop or in your bag.
