Altostratus clouds often indicate that stormy weather is on the way, so when you see those bad boys rolling in on a winter afternoon make sure to set up tomorrow's early start, work on your best sick voice, and have the Quiksilver Altostratus 2L Gore-Tex Bib Pant close by. Offering durable waterproofing and high breathability, this pant will keep you dry and comfortable on even the deepest powder days. The fully-taped seams ensure a water-tight seal against the elements, while the full bib design offers the added coverage you need when you're flying through waist-deep powder. Mesh-lined vents on the outside leg will cool you down when you start to work up a sweat, but won't let snow in if you forget to zip them back up. Working hard on the same front are the stretchy boot gaiters that keep all that snow from creeping in your boot or pant leg, and rounding things out are pockets on the chest and leg, giving you easy storage for gear, tools, and maps.
