I was already sold on this classic jacket before I bought it, since I have often borrowed my boyfriend's Nuptse (which he has had for about 8 years). This new one has the same fabulous down warmth, but is slightly slimmer, has a wonderful microfleece collar, a convenient stow/stuff pocket, and an even better ripstop nylon shell. An absolute MUST item for backpacking, it has superior warmth that packs small and (so far) seems tough enough for travel.
The only negative is that some feathers still poke through, so a fabric that is more resistant to that would be the only improvement I could recommend.
