I recently purchased a Wested Raiders jacket from G-Mann, and I noticed that the action pleat is MUCH deeper in the new one than in my older one. I think the depth of my original is about 1 inch, whereas my new jacket has a nearly 2 inch deep pleat. Is there a design advantage to this? I've noticed that the back panel doesn't sit quite the same as my other jacket (it tends to bow out when I'm standing straight up) but this may be due to the newness of the jacket. Is this the reason Wested offers the elastic in their jackets now, and how would I know if mine has the elastic? Any input is appreciated.
