Arc'teryx Calyx Pant
Here's what other sites are saying:
Designed with a host of climbing-specific features, the Arc'teryx Women's Calyx Pant is your go-to choice for long summer days spent at the crag. The light cotton canvas blend withstands abrasion from rough granite and sandstone while the knitted, fold-over waistband fits comfortably beneath your harness. Articulated knees and a gusseted crotch allow you to move without restriction, and the drawcord hems keep the pants from limiting your vision during technical footwork sequences.
The Calyx Pant is a hard-wearing, fully featured pant with generous articulation through the knees. A knit waistband rolls up to fit under the harness while reinforced knees and elastic draws at the hem and back patch pockets reflect climbing influence. This is the perfect climbing pant.
