John wrote a review of Castelli Presto Due Bib Short - Men's on September 30, 2014
Familiarity: I've used it once or twice and have initial impressions
I have the red ones and they look great and they ride fine, but the quality of the material cuts and stitching is lacking. It broke two stitches where it attaches the chamois to the shorts on my first time using them, I was so frustrated. I expected a lot more from he brand. Right in the front crotch area. I also ordered Velocissimo bibs but they had the same qualirty issues with the stitching. Both are made in China I noticed.
My Castelli Enduro bibs are stitched together much more nicely as are my Castelli Endurance shorts with the X2. Both made in Morocco and the stitching is good and what I expect from products in this price range. I kept these and returned the Velocissimo as well. The Castelli bibs made in Morocco and El Salvadore seem better constructed.
