WTB jackets with 3D collars (-S preferred. no -GT, but -WS is acceptable) sz Medium, EU preferred Like J36-S etc

Of course you can also open up the jacket with the secondary torso zipper, but since that zipper is used for ventilation as well as liner access, I usually don't touch it so that the zipper head position isn't changed for when I need liner access. As such I mostly just use the collar zipper and leave the main zipper opened if I need more ventilation. Pretty handy.

I'd appreciate a short review of the J36-WS as soon as anyone gets their hands on it

Lol, you know CH is partly made from synthetic fibres as well, right? CH is as much plastic as DS, really.
