Arc'teryx Alpha SL Pant - Women's - $139.27

You can easily stash the super lightweight Arc'teryx Women's Alpha SL Pant until you need them for a rainy or snowy ascent. Made from Gore-Tex Paclite, these waterproof shells weigh in at less than a half pound and give you full protection without sacrificing breathability. In fact, the Alpha SL Pant is the lightest waterproof pant that Arc'teryx offers. WaterTight ankle side zips make entry a snap and work as vents when you need to dump heat. And as always, Arc'teryx designed this pant with a feminine cut specifically to look good on active ladies. *Available for US shipment only. - $139.27
