I'm probably the wrong person to ask lol I've owned mine for around 2 years, and it pretty much never gets worn. The main reason being it's just sized too weird for me. It fits me perfectly in the body, but the arms are way too long, and way too wide, it just feels ridiculous to wear. I also had some issues with my liner pulling apart at the armpit seam, the brass hardware started rusting for some strange reason. My biggest gripe was with the construction of the sleeves, instead of a solid sleeve, with the stripes attached, it was all done in pieces, meaning that if you were to try to remove the stripe to make it more SA, you'd lose the entire sleeve of your jacket. However, Jorge at Heron, saw my posts here talking about my issues, and volunteered to fix my jacket at no cost to me whatsoever, but when I messaged him about returning it, communication stopped completely, and that was over a year ago. So it was a nice gesture, but in the end went absolutely nowhere. If you go to pages 72 and 73 I believe, you can see my posts and I even posted a few pictures.
All that being said, Heron's new X-1 does look leagues better than the version I have collecting dust in my closet. And as far as I know, the new X-1 doesn't have any of those faults that I had with mine. I wouldn't be worried about the jacket you're getting, I know they've put A LOT of time into getting this version more durable, built better, and more screen accurate. I'd love to have one of their new X-1's, but with the lack of costumer service I experienced with Jorge previously, I don't see that happening anytime soon.
