First time with the Progretto X2 seat pad - love it. Went with the compression version of these bibs & they are more work to get on, but after 50 miles of pedaling you can tell a difference.
The new pad is very nice, and I like it better than the previous Castelli pads. The fit up front is much better too. Straps are comfortable and work well. I'm 5'7 132 lb and have worn medium Castelli bibs in the past but this one is a small and fits perfectly. Snug, but that's my preference.
