Tackle the trails in pants that move with you. The KUHL HORIZN Convertible hiking pants are constructed of REFLEX SOFTSHELL fabric, a soft ripstop fabric with stretch. Quick dry and breathable, REFLEX SOFTSHELL retains its shape, and the high twist yarn displays visible depth. UPF 50 provides sun protection. For added strength and durability, the HORIZN is stitched with the same nylon thread used in climbing harnesses. Saddle stitch seams reduce bulk for a truly inspired fit. Converts to shorts with patented stealth zip-off system.
