They do different things some years - this link below gives a flavour (I did my research before buying something for once) there is more chatter out there and I seem to remember seeing something by Klim themselves but can’t find it now. https://www.advrider.com/f/threads/klim-latitude-generations.1253584/
Update. The stock I highlighted earlier at Louis is the 2022, 4th Gen, version but they have stock up to 2XL(eu 56) and it’s still under €600. The 2023, 5th Gen, isn’t available from Klim yet but both the Klim website and the sole dealer here in ROI are listing it €980 . Similar price uplifts on the pants. Apply your own FX rate. If it weren’t for the fact I know Im between a 2XL and 3XL (and really do need to try it on first) I’d order the discounted ‘22 stock from Louis for a €380 saving is very significant.
