Not great

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: XL

Frustrating jacket. I like the way it looks and fits a lot. However, it's not worth it. Within a few days of wearing it, the fill/primaloft started coming out of the fabric. This has only gotten worse. Anywhere friction is generated, the jacket is now covered with fuzz balls. When you pull on them, you can see it pulling out the insulation. Also, the zipper was very difficult at first, although it has started working better with continued use.

Great Jacket

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

The fit is great and it is very comfortable on the skin. I can wear it over a t-shirt down to about 40F. It has held up to light rain well and haven't used it in heavy rain. Overall, the jacket exudes quality and is a great product.

Should have returned it

  • Familiarity: I've used it once or twice and have initial impressions

The zipper on this jacket is poor quality. It's a problem every time I pt it on. I should have returned it when I could have.
