 "summary": "A premium, very breathable running fleece that Treeline chose as its best fleece: cozier and airier than a wind shell in dry cold, but a narrow-use piece that needs a shell over it when it's windy or wet.",
 "best_for": "Calm, dry runs from about the mid-20s to 40°F, or as a breathable midlayer under a shell on colder days.",
 "not_for": "Windy or wet conditions on its own, or shoppers watching their budget.",
 "downsides": [
  "Expensive at $200",
  "Blocks far less wind than a shell",
  "Some owner reviews call the cut boxy or large"
