Mountain HardwearKillswitch Composite 3-in1 Insulated Jacket - Men's

For a bit of everything.

When you want a jacket that can handle anything from frigid January pow days to early April slush-fests and pond-skimming, grab the Mountain Hardwear Killswitch Composite 3-in-1 Insulated Jacket. The outer shell features 2-layer construction that repels water and slices through wind, with taped seams to seal water from making its way in through the cracks, and under-arm zips to offer ventilation. A removable inner jacket combines the shell with fleece, and paneled synthetic down, for extra warmth on icy days, but either can be worn on their own if the weather isn't so demanding. Pulling all of the stops, the jacket features all of the bells and whistles you want from a burly winter jacket including a powder skirt, helmet-compatible hood, zippered pass pockets, and goggle wipe. Remove the liner to wear as the perfect après fleece or for fall and spring hikes, throw on the shell for spring skiing, or days when the temps are warm but there's still a sharp breeze. With versatility from your jacket you'll always be able to pull together a piece for whatever riding the day has to offer.

Not up to the hype

  • Fit: Runs small

I purchased this hoping to replace an older jacket, but it fell short in my estimation. My biggest issue was with the insulation in the arms. While the jacket fit well and kept my torso nice and warm, the arms were a different story. The cold started in the forearms and traveled up to the shoulders. I expect to use this while on backpacking trips in the Smokies, and it couldn't handle 25 degree temps in my front yard.
