Ride 120-175 mi/week and have many kits and short combinations, but always like to keep 3 or 4 pairs of standard black shorts in the rotation. These are my first pair of Assos, and they are my immediate favorite due to comfort. Zero chafing with the semi-detached pad design.
Waist and thigh bands are fairly loose and expansive, which I don't need but don't mind either. Think they're designed to work with wide range of belly and thigh contours. These aren't Assos' high end performance shorts. They're perfect for rides up to 60 mi though, IMO.
Note that these run BIG. I first ordered L size due to Assos' reputation of things running tight (my waist is 32.5, wt 160). I swam in them and returned them for M, which are very comfortable.
Assos shorts have a comfortable pad, but so do many others. The thigh grip is better than most, though, and the stretchy-ness of the fabric leads to a general feel of comfort and ease when riding. The waist stays comfortable over a full day as well. But real value comes in the durability of the fabric. I'm still using my first pair of these after a number of years (five), and the fabric has faded recently, but not failed. Every other pair of shorts or bibs I've had gets maybe two years before fabric transparency happens. These just keep going. An excellent value.
The Material of the short is nice soft quality, but lacks compression. The Pad is the Best I've used. It fits me just right. I often have irritation in the groin area, but not with this pad. The Short does run large. I wear a Medium in Pearl Izumi, and a Large in Castelli, I purchased a Medium in this short and it is bigger then a large in Castelli.
Have many pairs of these, as I prefer over bib shorts for comfort, and the pad is excellent. Only disappointment is the colour choice - black only, no leg stripes. Time for Assoss to add some stripes!
