The Kuhl Men's Liberator Convertible Pants employ the revolutionary DryPoint technology which pulls moisture away froma nylon inner layer towardsa cotton outerskin, allowing it to evaporate and resulting in constant cooling. The Liberator Convertible Pants also feature Kuhl's Rhino technology which layers exterior non-stretch fabrics on top of stretchy, softer fabrics to allow for a natural stretch and greater movement. To increase stretch and mobility the pants have a Born Free Gusseted Crotch and articulated knees which make reaching that extra inch when bouldering or scrambling easy.
