I wanted a new pair of assos bibs due to the excellent performance I have had with past pairs. I have used these for about 500 miles of mixed terrain riding on a non-suspension gravel bike at this point and so far they have been great! The padding is noticeably thicker than road shorts, which has been great for trail riding. I use the leg pockets for extra snacks, the pocket holds items so tightly I forget they are there sometimes, however the pockets are transparent so you can see what you have stashed. I use a jersey with pockets so I have not used the back pockets as much, but could be used to hold flatter items. Overall, these are a great pair of shorts with more of a gravel/trail oriented design and some nifty features!
As a long time Assos Bibs/Shorts user I was pleased when they applied their talents to Gravel Ridin' gear. Chamois thickness & density, stealthy pockets (unnoticed until needed), and subtle difference in fabric "feel" combine to make the Kiespanzer my new favorite bibs for all (and any) surface riding. I am 5'8" 165# 35"waist and M fits just fine.
