The Patagonia Men's Altiva Alpine Pants are fully featured lightweight soft-shelled pants with added durability for long alpine rock routes. This pair of technical pants are made of stretchy polyester/spandex blend for complete mobility, and the recycled nylon/spandex paneling provides extra protection from rock and abrasion. Enjoy the articulated pattern that allows all-day comfort under a harness and the low-profile waistband that allows you to stay comfortable while wearing a harness or backpack waistbelt. Additionally, these pants have a durable water repellant finish, secure front pockets, and a right-thigh security zip pocket with a lie-flat construction designed for easy access. The Patagonia Men's Altiva Alpine Pants are designed for climbing and offer you all-day movement for when you're above the tree line.
