The Black Diamond Alpine Light men's technical pants are a premium designed garment for mountaineers, climbers, and hikers seeking the ideal balance between minimal weight and maximum functionality on their mountain adventures. Weighing just 311 g, they represent an excellent three-season solution for use from spring to autumn. Thanks to their extremely lightweight and packable construction, they take up negligible space in a backpack while offering reliable protection against wind and changeable mountain weather.

They are crafted from a durable yet lightweight fabric with a density of 148 g/m², consisting of 85% polyamide (nylon) for abrasion resistance against rock and 15% elastane for unrestricted 4-way stretch. The outer layer is treated with an eco-friendly PFC/PFAS-free DWR water-repellent finish, ensuring moisture and dirt slide off the surface. At the same time, the fabric wicks away body moisture excellently and dries quickly, ensuring a high level of comfort during intense ascents.

The cut is purposefully tailored for freedom of movement on rock faces and steep trails; articulated knees and a gusseted crotch allow for comfortable high steps. An integrated low-profile belt with an aluminum buckle ensures stability and easy adjustment without interfering with a climbing harness or backpack hip belt. The leg cuffs adjust precisely with a CordLock drawstring, and functional zippered pockets (two front and one thigh pocket) remain fully accessible even while wearing a climbing harness.
