The prAna Stretch Zion Top-Out Pant keeps us cool and protected on the approach with its wicking, sun-blocking fabrication, so we're really only chasing the shade for the friction. As we work our project, the strong nylon fibers resist tears and abrasions against the rock, and the cinchable hems stay out of our way. When we finally throw our heel for the mantel, the woven-in stretch and inseam gusset ensure its not our 'fit that holds us back from the send.
