Great fit on the bike - the cut could be better

I'm 195cm, 80kg, 81cm waist - the XL bibs fit the way I like - snug all around and not too long in the legs. These shorts have good compression and they stay in place for the entire ride. I've used these a number of times on rides up to 120km. The chamois is comfortable and is in the right place. The front of the shorts is cut pretty high so isn't very well suited for natural breaks. The fabric is pretty light weight so I'll have to see how they hold up over time. Given the price, I'd buy these again.

Molto classici come modello, si potrebbe abbassare lo spacco anteriore delle bretelle per agevolare i bisogni fisiologici.

Nice Bibs

They compress nicely without being restrictive or too tight. The pad is great--have worn it on rides of 3+ hours with no complaints.

a good light summertime bib short

I bought this PRIMO for the summer season. It fits well in the right size and nothing is pinching. The legs can move without resistance. The material is thin so let's hope it lasts a long time. On my opinion the seatpad should be a little bit thicker. But on the end it is a good bib to try out Santini on a good level of quality.

I bought these shorts to replace an old worn out pair. I have to say I absolutely love them. They are really comfortable and feel extremely light, like you're not wearing anything! The pad is very comfortable and the leg grippers and compression brilliant. Always my 'go to' shorts.

Excellent Bib-Shorts

great for the price

This has become by day-to-day bibs for commuting to work. For longer weekend rides I'll wear a bib with a slightly better seat pad. Looks good too.

Love these bibs, very comfortable and the pad isn’t bulky or uncomfortable to wear for hours.
