Some in-person impressions of several of the pieces from this first release:
J61-GTV: I have never been particularly enamored of any iteration of this coat, so I didn't bother to try this one on. Looked fairly similar to the -WS and -GT versions which I had seen / tried on during previous releases; obviously your mileage will vary if this is a style you like. Didn't look like anything drastically different from the earlier iterations to me, though. Admittedly I am not the right person to ask for details about this one.
J79TS-GT: This is a very boxy cut, much larger for the tagged size than I would have expected. My friend who usually wears L or XL in Acronym jackets could easily fit into the M on this; for my own frame I think it is a bit too large (5'9" 125lbs). The front pocket array is interesting, but doesn't feel like it would be as useful as the J1A to me. I did like the look of the hood, despite not usually liking jackets where it cannot be detached or stowed.
J29-PX: This looked better in person to me than in the photos. The fabric doesn't seem as translucent as the previous -PX coat, and the fuzzy lining in the body was an unexpected (and in my opinion, nice) touch. The collar in folded-down blazer mode is a little questionable given the thickness of the fabric, but I think it looks pretty great standing up, and I like the pocket array on this one. This was the one piece I actually ended up purchasing, though I was tempted by a couple others.
J65-AJ: I liked the general look of this pattern in the -AJ material quite a lot. The silhouette flares outwards noticeably in profile (not actually pictured in any of the official product shots), which on my frame looked a bit funny -- it's not a particularly even flare, either; it gave me sort of an artificial paunch. On someone with a sturdier build where this fits more tight to the frame, I think it would look really great, though. Definitely more interesting to me than the boiled wool versions of this jacket from the earlier season.
J77-AM: This was the piece I was most tempted to purchase aside from the J29. I tried it on over a black buttondown, and it looked great. The hood is not bulky at all, so I didn't mind it being attached to the sweater. My favorite detail was the shoulder pockets; they give it a bit of an aggressive silhouette without being over the top. I don't know how this would look with something other than a long-sleeve black shirt under it, and the price feels a bit too high for what it is, but I did quite like this one.
P34-*: I was a bit torn over this one. I tried it on in the -E fabric, which I liked a lot and thought was suitable for the pant -- I own a J33-E, which is a nice pattern, but I think the -E fabric probably works better for pants than jackets, though this is a personal preference. I didn't try on the -S version but probably wouldn't personally consider it, since I own a lot of pairs of Stotz pants and liked the lighter feel of the -E fabric. I also really liked the tapered silhouette of the ankle, which broke at just the right height for me wearing sneakers. However, the waistline on these pants is very large -- impossible for me without a belt, and if I unclipped my belt to go to the bathroom I'd have to carefully hold them up, which isn't something I'd really like to worry about in practice. I also found the cargo pocket array a bit overwrought and somehow uninspiring. I would be very interested in a version of this pant without the cargo pockets though (or at least without the zippered pocket on the left), and a smaller waistband for the tagged size.
NG5-AK: I didn't put this one on, but this was very soft and comfortable to the touch. It is quite wispy; seemingly moreso to me than the long -AK neck gaiter with the "2-part hem" from a few seasons back as I recall, though I could be misremembering. Kind of expensive for what you're getting though.
I didn't get to see the hat in person, but assuming it is the same fabric as the J65, I think it'd be quite cozy. I don't wear a lot of hats though, so I don't have strong feelings on the style.
