For the mountain man who needs it all in one three layer shell pant, Norrona made the Men's Trollveggen dri3 Pant. This mountain slayer is made from dri3, which is a ultra thin, stretchy, non porous, hydrophilic membrane that is highly waterproof and breathable. the Trollveggen also gets a DWR treatment and taped seams to further help repel that cold wet stuff as you conquer the winter hills in your neck of the woods. The pants have a zip off bib in Norrona's flex1 softshell material, so it's breathable, yet fully functional when you need it when you don't, just take it off. The drop seat construction with venting zips can be open wherever you like. Other features include YKK water resistant zippers, a custom fit waist system so you can dial it in the way you like, and articulated knees for freedom of motion. Stash your maps, snacks and such in the two handwarmer pockets or the thigh bellows pocket. And before you start crushing it out there, be sure to fix the elastic gaiters with hooks around your boots to keep snow out when it gets deep.
