Your climbing partner is very uncomfortable with his rigid jacket that restricts his mobility -- it's too bad he doesn't have the Arc'teryx Men's Fortrez Hoodie Fleece Jacket on like you do. This fleece uses Polartec Power Stretch fabric to keep you fully mobile on the mountain, and it's surprisingly breathable so you stay comfortable, too. A Hardface coating increases this fleece's durability against abrasions from rocky terrain. Plus, Arc'teryx added an integrated neck gaiter that doubles as a balaclava, so you don't have that snot-riddled look your belay buddy is sporting along with his uncomfortable jacket.

A trim fit pulls the Fortrez close to your body for layering a waterproof shell over it during poor conditions. Its Scuba hood slides across your head tightly to seal out any strong gusts of wind. Articulated elbows and gusseted underarms increase the range of motion you need to pull past those technical cruxes. A drop-tail hem offers more coverage when you bend over to brush debris off your shoes. And flatlock seams reduce bulk for easy layering with your winter wardrobe.
