I'm a huge fan of the $40 bibs from theblackbibs-dot-com. I have one pair of their "Black Bibs Plus" and one pair of their "Black Bibs Ultimate" in addition to 4-6 pair of their regular $40 "Black Bibs".

I'm a big guy - 6'-1" and 225-230 lbs. I ride 7k+ annually, almost all on these bibs. I have other more expensive bibs from other companies. I rarely wear them. I've ridden 67 centuries in the past 4 years, all with my "Black Bibs" - no problems.

Just thankful I found something that works for my posterior!
