 "summary": "A breathable, stretchy insulated hoody made for stop-and-go aerobic effort and iRunFar's top winter running jacket this season; the lighter fill should suit running better than earlier, warmer versions, but it's pricey and not weatherproof.",

 "not_for": "Wet weather or runs much above freezing, where it is likely to feel too warm.",
 "downsides": [
  "Expensive at about $300",
  "Not waterproof; relies on a DWR finish",

   "finding": "Named it the best winter running jacket ($300). The new version cuts FullRange fill from 60 to 40 g/m², which the reviewers expect to suit variable-pace running; they found the earlier version comfortable from about 20°F down to -20°F but sometimes too warm above that. It fits in a hydration vest and layers under a shell; full testing of the new version was still pending."
