Great lightweight jacket

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: Small

I'm generally between XS and S women's tops and got a small. Fits great with a heavy baselayer or light casual shirt, but don't expect to fit a big sweater underneath. Blue color is awesome and very bright.

Blocks wind fairly well. It's meant to be lightweight insulation - I'm comfortable in it down to 40F with a midweight baselayer doing light/moderate activity. Wore it in 10F with a midweight baselayer and a lightweight fleece doing light activity and was pretty chilly, as expected. Both experiences above were with associated weather appropriate pants, gloves, hat, etc and no other top layers except those listed.
