Ultralight, packable, waterproof and breathable GORE-TEX® alpine pant designed for emergency weather protection.  Alpha Series: Climbing and alpine focused systems | SL: Super light.

$269.00
Specs Sizing
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.
 
Maximum Versitility
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.
 
Zip It
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.

Good rain pants

Not a big fan of baggy anything. I definitely tend to like more sporty cuts. With that said... these pants fit just like they are supposed to. Slightly baggy. I labeled them "true to size" b/c thats how they are supposed to fit. They are easy to put on without the need to remove crampons.

Use Situation: I put them on like any other pair of pants.
