My wife bought this insulation layer jacket to go along with the rain shell posted below.

Details

• Very stretchy
• Active Fit. Trim, close to body fit
• Hydrophobic 800-fill down
• Weight: 14.8 oz / 420 g

So far she’s only worn it a few times.  I’ll return with an update.

Update: She wears it every day and so far so good.  Keeps her warm, not too delicate, perfect body-hugging fit.
