Though $30 more than previous years Mille bibs, these are definitely better built. The X-Frame straps are cooler on warm rides, the chamois is a tad wider which helped me, the leg grippers are much better than the old school silicone bands, and lastly the junk cradle is a bit better. I have done several 4-6hr rides in these and really just forgot about them where in the past I would have to readjust the chamois to get the seams off my sit bone. I use these for endurance MTB and I have used Pearl Izumi, Giordana, Jakroo, Bioracer bibs as a comparison.
