Delivering optimized performance for minimal weight, the ultralight Alpha SL Pant packs small, ready to provide emergency weather protection when needed. N40r GORE-TEX® fabric with Paclite® product technology is waterproof, breathable and exceptionally light. The nylon ripstop face offers some abrasion and tear resistance. Where higher levels of durability are required, Arc’teryx uses hardwearing N150p-X GORE-TEX® fabric.
Built to handle wide range of alpine pursuits while weighing as little as is functionally possible, the Alpha SL Pant uses only essential features. Drawcords at the hem work with a tuck away bootlace hook to provide a secure, full coverage fit, even while climbing. The dual waist adjusters fit comfortably under a pack or harness, and the trim leg fit reduces crampon snags and allows for more effective layering. The Athletic fit with e3D patterning maximizes ergonomic freedom.
An example of the Arc’teryx commitment to performance focused design is the Alpha SL’s side zip system. Running the length of the pant, the zipper separates completely, making it easy to put on and take off the pant as weather shifts. By partially unzipping each side at the top, the system creates a drop seat, a feature that is truly appreciated when needed. Arc’teryx WaterTight™ zippers are used for a streamlined, snag free profile.
