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.
Rigorously tested in some of Norway's roughest terrain (i.e. cold, wet, rocky, and inhabitable) by top climbers, the Norrona Men's Trollveggen Dri3 Climbing Bib offers you waterproof windproof breathable three-layer protection and the comfort of a two-way stretch membrane. Norrona didn't skimp on the details either; water-resistant YKK zippers and fully taped seams seal the cracks, a cargo pocket stores your energy snack, adjustable hems customize comfort, and zippered venting dumps the heat from your climb. Norrona also reinforced the ankle zones with Superfabric, so you don't rip your investment to shreds and lose confidance while you're clinging to the side of a giant rock or climbing up a frozen waterfall. Integrated suspenders improve the comfort and stability of the Trollveggen Dri3 Climbing Bib. Norrona's medium fit optimizes movement without leaving loose parts for gear to snag on.
