The KUHL Rydr Pant is cut from Kuhl's exclusive combed cotton euro-twill fabric that has been slightly brushed for an even softer hand. However, one look and you will realize these are much tougher than the denim in your closet. Once you put them on you will instantly recognize the anatomical design which follows the natural shape and curves of your body, providing the ultimate in fit and comfort.The classic five pocket design is anything but traditional. Gusseted crotch and articulated knees allow unrestricted freedom to move. So tough even the pockets are reinforced in those high wear areas.
