Until this point I had only ever worn shorts. Been hearing the hype for ever about bibs from a friend so I decided to buy some. I had only every worn Pearl Izumi shorts, but I had been using Castelli jerseys for a few years and loved them so I though I would try their bibs. I bought two pair of the Presto and two pair of the Endurance Bibs. The biggest thing I have to say about these is the chamois is so much better than the Pearl Izumi Elite In-R-Cool shorts I had been using. I had a few sores from my old shorts and as soon as I got on the bike with the Castelli Prestos I did not feel any pain the whole 30 mi ride. Heck after the first 10 minutes I was trying to remember what all colors they had so I could order some more and just what I should say in my review.
The next day I tried out the Endurance and they are just as comfortable. Which I guess says something to how good the Kiss3 chamois is because I thought they both felt great. I do think the Progetto X2 would be better for longer rides though. I rode 55 mi on the Endurance and had no pain. I was sold. I will also say that I really liked the leg grips on these. They stay in place great but there is no feel of the rubber or gel on your leg gripping or pulling hair when you move them. I ended up ordering all three colors in the Endurance 4 pairs of the Preston and one pair of the Velocissimo Equip to go with an Acid Green jersey I had. You seem to get so much more choices in color when you buy bibs compared to regular shorts.
