I am told that the North Face Nuptse 2 will zip into this jacket. Is that correct?
No. It won't. It will zip into Mountain light shell or triclimate, but NOT insulated.
Frankly, I'm disappointed with the Northface product. I've purchased Northface in the past and was very happy. This jacket has a cheaper zipper, is not warm at all and I have to wear sweaters under it.. (I'm in Pittsburgh) the Hood comes down over my eyes so I can't see. For the money I would not buy this jacket again.
This jacket does not have any secondary zippers that allow anything to be zipped in. The jacket does allow for enough room to wear a fleece vest, while still maintaining a proper fit.
