Got the S5 Uno's.
Love the chamois - it's friggin huge! Which is nice because I was getting cut up at the tops of my thighs by the seams of my other shorts, I don't think I can ever go back.
Fabric is delicate, not the bullet-proof feel of cheap $40 bibs - but it's waaay more breathable than anything I've ever tried. I think it's give and take here. Anyone crash on Assos bibs yet? Trashed?
Gonna get more for sure - but I might also look to get a pair of Rapha [depending on their chamois size].
