Boure Elite bibshorts
I picked up two pair in the "Wade's World" scratch and dent section of their site
http://boure.com/ . The stuff is apparently designed by Ned Overend of road/mountain/triathlon/runner fame, it's made in Colorado and the prices are quite reasonable for the quality. This is the return policy from their website:
"Our 100% satisfaction guaranty is absolute. At any time you have tried them and decided you want to return them, we will refund the purchase price against your credit card or as credit against a different item. Satisfaction is defined by you, you have to be happy enough with them to keep them".
As for the bibs themselves, the fabric is pretty standard lycra, they're cut to fit properly in the cycling position, they have good but not too much compression, the upper is a breathable mesh and the braces are on the wide side which I prefer, there is no slippage off the shoulders. The leg grippers are pretty standard fair, not too tight but they also don't ride up, there is no ipod pocket and the logos are tasteful and not too flashy.
The chamois is one of the thinner one's I've tried, quite the opposite of the type one usually finds with Pearl, Giordana or Assos. However, with my Prologo saddle which is a bit more padded than say an SLR or a Toupe, the combination works very well (for me). If you prefer that your chamois not feel like you are wearing a diaper, these bibs are definitely worth checking out.
As for sizing, at 5'6" and 155 lbs. I take a medium in virtually every bib I've tried and I fit a medium in these as well. The people there answer the phone and are worth calling if you're not sure about sizing or the difference in their different models. So far these bibs have performed admirably up to and including a 67 miler.
