Arc'teryx Alpha SL Pant -

Before you leave for your alpine spring adventure, make sure you have the Arc'teryx Women's Alpha SL Pant in your expedition backpack. Made from Gore-Tex Paclite fabric, this waterproof, windproof, and breathable shell pant packs down to nearly nothing, weighs less than a pound, and offers you the kind of protection you require when a late winter storm rolls in. Full-length side zips make entry a snap and work as vents when you need to dump heat, while the Alpha SL's feminine, athletic fit makes you look good when you're working your way up a snowy face.


  • The lightest, most packable fabric from Gore-Tex PacLite uses a durable unlined membrane to keep you dry in the wettest conditions
  • High wear areas are reinforced with more abrasion-resistant face fabric for increased durability
  • Gore-Tex Paclite 2L fabric reinforces the high-wear areas for added abrasion resistance and longevity
  • Low profile waistband is adjustable from the rear; boot lace hooks and hem drawcords secure the pants to mountaineering boots


  • Athletic fit provides plenty of unrestricted mobility while you maneuver up and over a steep frozen waterfall or navigate through a treacherous maze of cliffs and crevasses
  • Low-profile waist adjustment system supplies a comfortable, secure, and custom fit


  • Full side zippers offer easy on/off over boots, and are angled to improve moisture protection and snag resistance while opened for venting

Weather and Wind:

  • Windproof waterproof/breathable GORE-TEX technology protection
  • Designed for those who truly believe less is more in the outdoors, Gore-Tex® PacLite® is durably waterproof and highly breathable
  • Waterproof, windproof, breathable Gore-Tex Paclite fabric seals out the snow and ice drips while allowing excess interior heat to escape so you stay dry and comfortable


  • Full-side zippers accommodate mountaineering or touring boots and help you dump excess heat quickly
  • Arc'teryx Alpha SL pants feature laminated WaterTight™ zippers


  • Boot lace hooks help keep the Alpha in place
  • Reinforced instep adds durability

The Alpha SL Pant is a waterproof alpine pant with full separating side zippers. Utilizing GORE-TEX fabric with Paclite product technology makes these pants windproof, and waterproof/breathable protection that is exceptionally compact. High wear areas are reinforced with more abrasion resistant N150p face fabric to increase longevity and retain light overall weight.


The best gear should help you reach the summit without distracting you or holding you back. The Arc'teryx Alpha SL pants do just that with high-performance materials and superior construction.
