The brands i've tried so far:
Raccmer jersey: They are "okay", pretty much what you expect from a decent aliexpress jersey, material feels cheap and it fits okay, fine for a commute but not on race day.
Spexcel bibs: They are "okay", i've found the leg grippers have quickly given up on life, the material is relatively good, the chamois is a bit short at the front for my liking but they are fine for anything under 2 hour ride - i just use it for commuting these days.
YKYWBIKE Bibs: Fabric is good quality, grippers are good, the chamois is better than the spexcel however not as long as i'd like it, only realm qualm is that it's a little bit short at the front for my liking, this is probably the high end of ali express brands. I wear it on longer rides and it's fine.
YKYWBIKE Jersey: The fabric is really weird, not like the cheaper ali brands but not like my "western" jerseys either, it feels like swimming clothes material, also no grippers on the arms. The fit is pretty good, I'd probably equate it to a lower end "serious" cycling jersey maybe something like a sportful?
x-tiger jersey: Shit, the material is really hot and not very comfortable, i never use it as it's too hot here to wear it.
