The longer the route, the more likely you'll need the Norrona Trollveggen Warm 2 Fleece Jacket to keep you warm while you climb in the alpine and chill during your portaledge slumber party. The long, cold climb requires durability and insulation, which is what the stretchy, fuzzy Polartec Thermal Pro fleece fabric does without adding too much weight to your pack or haul bag.
