Arc'teryx strategically employed different fabrics in the Men's Phase AR Hoodie so it not only keeps you comfortable on your cool-weather runs, but offers a smooth, low-bulk fit when you're wearing it under layers on the mountain. The insulating Phasic AR fabric is balanced by lighter-weight Phasic SL fabric under the arms for a touch of ventilation where you need it most. In addition, Arc'teryx updated both fabrics with smaller-gauge yarns to give the Phase AR Hoodie a softer feel against your skin.

  • Midweight Phasic AR fabric in the body and hood features a lofted inner surface that traps heat and a smooth outer face that slides easily under layers and resists pilling
  • Lightweight Phasic SL fabric in the underarm area provides enhanced breathability to regulate comfort during stop-and-go winter tours
  • Multidimensional polyester yarn in both Phasic fabrics wicks moisture with remarkable speed, while soft, fine polypropylene yarn features embedded silver-ion technology to fight odors
  • Mechanical stretch allows plenty of freedom of movement and a close fit
  • Flatlock seams won't chafe under pack straps or with repetitive motion
  • UPF 50-rated protection prevents sunburn on your high-altitude adventures

Great addition to the Phase line

    Tremendous hoody. I've used it for running in cool temps. Fit is trim, as it should be for a base/sole layer. I'm 5-10, 135 and the Small is comfortably snug. (I had a little trouble with chafing initially but some well-placed lubricant took care of that.) Arc's update to the Phase material does make it feel better against the skin, although the previous version would only bother me for about 4 seconds before I forgot about it. The hoody is warm but breathable. It's long enough to keep the chill off your mid-section. Sleeves are ample in length without being ridiculously long. Wouldn't have minded thumbholes, but they're not a must. The neck construction is very nice--material drapes to keep the chill off, but doesn't feel constricting. Hood is superb--good volume, close-but-not tight fit to balance warmth with air flow, and it stays on your head while running. This is a stripped-down garment--no pockets, no hood adjustments, no hem cinches. Only what you need. (Not sure the anti-stink treatment works, but maybe that's my fault.)
