I’m very happy with these bibs. The chamois is firm enough to give good support for many hours without being excessively plush. For context, I’m 6’1”, 170 lbs, with a 35” waist, 21” thighs, and 4” sit bone width. I initially ordered a Large based on the fit chart, but then exchanged for a Medium because the leg band of the L pair didn’t touch all the way around and the bibs just felt too loose in general. The exchange process was quick and trouble-free. Based on a closer reading of the fit chart I probably should have ordered an M in the first place but, well, online shopping. The fit of the M pair is just a little tight, which is what I prefer. The fit does feel more natural in riding position than standing up, which they note in the fit guide. The only flaw in the fit for me is that the chamois is just a touch wider than ideal for my narrow sit bones, but it’s not objectionably so and getting that perfect for everyone would probably require that Primal manufacture multiple chamois widths, driving up prices. At most I would have taken a half-star off for that but I can’t so I’m leaving it at 5: totally happy. I can’t review longevity yet because I haven’t ridden in these long enough, but I’ll try to remember to come back and do that in the future.
