Ok, these bibs have stood up to gravel training rides of 110 and 130 miles (177km and 209km), keeping me comfortable on long days in the saddle. The chamois is the best I've ever had (various shorts including PRO-level from Pearl Izumi, Bellwether, and a "single color name Bibs" bargain). Just the right width for my sit bones without any of that diaper effect. Also provides enough firm cushion for an 8.5-hour ride. Can't say that I can compare to Castelli or the other high-end brands, which are also twice the price.
I like the two large, stacked pockets in the rear rather than the three small vertical pockets most brands put there. If I put a phone or anything in the front pockets, I hardly even notice it there. The only thing I'd wish to change would be maybe one more inch of inseam to extend that great support lower on my thighs. The next big ride is doing the entire C&O Canal Towpath in one day, 184 miles (296km).
