I paid $100 for a pair of Castelli bib shorts and they are, well, simply not there. I use them on rides over 60 miles. Don't feel a thing. No saddle sores. No issues whatsoever. I've worn inexpensive shorts, medium price and these, and they are, hands down, the most comfortable shorts I have ever worn.
The way I see it, it's not an excess if I use them. You don't have to race to appreciate a great pair of shorts.
