Description
Description
The Arc'teryx Alpha SL Pant is an ultralight masterpiece designed for weight-conscious alpinists who refuse to compromise on weather protection. Engineered for high-output pursuits like front-pointing up technical ice or navigating unpredictable snowfields, these pants utilize the revolutionary GORE-TEX PRO ePE membrane. This sustainable, PFAS-free technology is bonded to a 20D Hadron™ face fabric—a proprietary material that offers an incredible strength-to-weight ratio, ensuring durability against jagged rock and ice while remaining remarkably breathable. At a mere 305g, they are the ultimate "just in case" shell, offering full waterproof and windproof security in a minimalist package that disappears into your pack. Whether you are climbing in the UK or the Alps, these pants provide the rugged, fast-and-light performance demanded by modern mountain athletes.
Performance is found in the details, and the Alpha SL Pant is loaded with functional features tailored for the vertical environment. The full-length side-separating zippers are a standout addition, allowing you to pull the pants on over bulky alpine boots and crampons the moment the weather turns. For a streamlined fit, the reinforced hems feature integrated adjusters and lace hooks that secure the pant to your boots, preventing snow ingress during deep transitions. Safety is subtly integrated with a built-in RECCO® reflector to aid search and rescue, while the bluesign® approved and dope-dyed materials highlight Arc'teryx’s commitment to sustainable manufacturing. Finished with the iconic Bird and word logos, these pants offer a precise, articulated fit that moves with you, providing a clean profile for focused climbing.
