Updated - I don't want people sizing wrong. These feel slimmer due to the material, but use the measurements as a guide - just know there will not be a lot of stretch.
Monkey typewriter time. The P24A-E came in and the most noticeable update seems to be they feel slimmer from prior iterations. Mediums fit me how smalls used to fit, and the first release small P24A-DS and P24A-S felt looser than these. My P34-DS mediums also were looser in the waist and baggier throughout the leg, so I would just say take your normal size, or go up if you're in between sizes.
I prefer how a normal reinforced hem sits on prior versions/other pants. The ease of adjustment with the draw cords for different shoes is convenient though, so it really just comes down to personal preference. Since I only had the first release, having the interior phone/organization pockets in the cargos is a welcome addition on this cut.
The E material maintains the pocket structure similar to stotz (my favorite fabric to pair with this style). I may be imagining it, but the cargo pockets also seem a little flatter than prior releases. You can fit things in the cargo pockets without bulging (34 DS) or sagging (24/30/38DS), so it is a good solution for low volume things. Personally, I would have preferred bigger pockets that leaned more into a BDU than tailored trouser look. The cargos wrap around the leg more like the P37. While I appreciate the hide in plain sight philosophy and the pant's ability to transition between multiple environments (who travels anymore anyways though), if I am going somewhere where cargo pants/BDUs wouldn't be acceptable, I would probably not be wearing 24a in the first place.
The fabric has been discussed already, so I will just say its properties suit the cut well. Hopefully we see a future release in different colors with some (subtle) contrasting hardware to highlight the features instead of masking them. The P30A-E navy with black hardware looked great and I certainly would not mind a 24A-E like that.
