Featuring our Dermizax three-ply, premium strech fabric, the MTN-X Apex 3L pants are fully seam-sealed for completely waterproof protection on snowy backcountry days. Designed with durability in mind, the pants feature a zipped hand pocket and a zipped cargo pocket that allows you to stash your valuables and grab them easily. The outseam zipped vents offer a cooler option when temps climb in springtime.
