They also said they got another shipment from Filson this morning that isn't listed on the site yet, and I'll post that info here as soon as I hear what they got.
I went up to the outlet again yesterday. Didn't get anything this time, but we talked for a bit, as they actually remembered me from a few months back. What was really cool is they showed me several items that were one-of-a-kind prototypes that never went to full production or had design changes in the final version. They were just mixed in with everything else. There was even a coat that will be going to production in a few months, but they happened to get a sample or something. Pretty neat stuff.
The SF (Seattle Fit) stuff is so confusing, since there's identical products with the Seattle Fit and the normal (Alaskan Fit, I think they call it), but nowhere on the garment does it say which one you're looking at. That stuff is so new that there isn't much of that line yet at the outlet, but there's always something great there. I didn't get anything this time (it was more of a a Christmas research visit for my wife), but last time I got two $400+ coats for $99 each (both size S). As for the for the prototype, I don't remember much about it other than it was a green coat; I was looking at lots of stuff. One disappointing thing I encountered worth noting is one of the thinner new coats had a really flimsy plastic zipper, a far cry from the usual heavy zippers Filson uses. Hopefully they'll abandon that direction.
