Not quite in the same category as a Packlite but my Decathlon (walkers not cycling) softshell has huge pitzips and is thick enough for the winter chill, yet to to let in any water even after 2 winters & is cheap as chips.
When last I looked (a while back), these more packable jacket seemed to have pitzips:
DHB Signal, Endura Venturi II & some versions of the Endura Flyte jacket.
Annoys me throughly that they keep going on about jackets materials being “breathable”, yet none of them will actually deal with the someone sweating while doing intensive activity.. say like cycling!
Put some fricken pitzips in and it would! I mourn the day Altura [IIRC] sold out to Wiggle, as they used to produce a great jacket with pitzips
