@init616 That was a consideration for me as well. For me, I live in a hot and dry climate (in the summer), where only shirt sleeves are enough 6 months of the year. October through May though I wanted a leather. I've found in the last couple of weeks that this jacket is quite good with only a dress shirt, tee, or light/medium baselayer underneath in my daily range of 0-23C or so in the winter. The leather is thick, unlike any denim type 3 I've ever worn. Probably not the best choice in 35C or higher.
The break-in of the jacket has to be one of its best features as well. A bit of rain or sprayed water and wearing the jacket, stretching out the shoulders, back, and chest, the jacket just conforms brilliantly to your body, rolls forming on the arms. Super cool. Here it is two weeks in, wearing 10 of the 12 days or so. I used a butter knife to stretch the button holes a bit, as it's a bitch to button when new--your fingers will thank you.
Another sweet feature is the interior "gun" pockets. In my jacket, the right inside pocket is noticeably deeper than that on the left--likely variability in mfg so if important for you, good to check with the guys on the jacket they send you. I'm left handed though, so all good. Not that it is relevant in the UK, but that right pocket easily fits a 4" Glock 19 or Walther PPQ without printing on the outside of the jacket. Definitely brilliant thick leather that softens up quickly but keeps its shape.
