I own both versions of the McKenzie and enjoy wearing both of them but the chamois is certainly better on the pro model, a good bit thicker it seems and more dense so it's very comfortable for me. The legs come down to my knees with the XL, I'm 5'9' 210lbs, and the material feels thick and provides good compression. For days above 85 degrees with humidity I'm more likely to wear something lighter but these aren't swelteringly hot by any means. Most days I prefer wearing these over my Assos summer bibs as they fit the well-nourished American body type better. The shoulder straps are nice and wide so I never feel them digging in and the 'waistline' is high so it helps to keep any excess baggage from spilling over the edges. When these are on sale I believe they offer a pretty good value.
Nicer material and nicer chamois then their regular version, but no leg grippers at the knees so depending on your leg shape you could have lose material flapping in the wind due to the longer inseam on this pro version. I returned this one and will either buy a second pair of PI Pro or the regular ProCorsa McKenzie.
This is a nicely made bib - certainly comparable to the Pearl PRO bib I usually wear, but with a bit nicer chamois. The fabric provides nice compression that doesn't loosen up during long rides like some of the less expensive shorts I've owned. Very nice laser cut straps that are plenty stretchy.
These are extraordinary bibs! They fit great, they feel great. If purchasing at regular price I'm not sure they are worth the extra money compared to the regular Mackenzie Summit bibs, but I also haven't been using them that long, so they may prove to outlast the regular Mackenzie. In any case, excellent product!
Tried these due to a good deal offered while buying some other items. They are not bad other than the section at the end of each leg is very, very tight. I ordered small and that has always worked for me with other brands. I am 5' 7" and about 135 lbs. Maybe it will loosen with use?
I have a couple of pairs of the Summit bibshorts and have been impressed with their quality and comfort, particularly for the price.
The Pro version is a nice step up. The fabric feels a bit softer, while retaining better compression over a long ride. I like the slightly longer leg length. Seems just about perfect now.
The chamois in the regular Summit is quite nice, but this one is even a bit better.
