I have 2 of these in different colors, a great option for very warm rides: seems to do best -- for me at least -- in the 75-90 degree range. (90+ I'm reaching for the Castelli Climber's A/C jersey or something similar.) Fabric is lightweight and stretchy, feels great against the skin. It's form-fitting without being a super tight race fight. (I'm 5'9" w/ a 40 chest and wear a L.) The zipper is very easy to navigate when lowering during climbs and pulling back up for descents. The lack of design/branding is a big plus in my book, makes it easy to combine with various different shorts regardless of brand. Keep in mind that the white version is a bit transparent; I think the main product photo for the white ("ivory") is very accurate in this regard.
My only complaint is about the rear lower hem. It doesn't seem to stay flat, kind of folds up under itself during rides. Not a major complaint; not worth taking off a star, and might be due to my size. But something I've noticed in comparison to other jerseys I have from Giordana and Assos that don't have this problem. Regardless, fills in well for the very warm (but not hot) riding range.
Need a jersey for hot weather riding in central TX. This A/C jersey is form-fitting without feeling constrictive; length is just right (I'm 5'9" w/ 40 chest and wear a L); pockets are relatively tight despite being an ultralight jersey. Overall excellent performance in hot (85+ degree) weather. Keep in mind it's very transparent, as expected with a jersey like this. My only minor complaint is that the sleeve length is a little long, but that might just be my sizing.
Very impressed with the overall material and fit quality of these bibs. Especially for the price. I appreciate that the inseam is long enough and the shoulder straps are also long enough compared to several other brands.
The chamois has also proven to be very comfortable. I've used these for about 10 rides or so this far and love them.
The only possible negative is the shoulder strap material is the same as the rest of the bibs, so can be a little warmer than others that might use a lighter mesh material in this area.
PI definitely hit the mark with these shorts compared to previous iterations, with similarly cushy chamois that's now more fitted and less compressive than older versions. It does a nice job of cushioning on long rides ensuring my perineum doesn't get sore like it does with other brands. I also like how it extends further forward to a bit beyond the perineum, to cushion my man parts just enough to avoid numbness and damp down hard road vibrations, without those parts feeling like they're being stuffed up into my intestines.
The main body fabric is a wonderful blend of stretchy, while being form-fitting and compressive, and it breathes well and doesn't heat up excessively in 90+ degree temps. At 6'3" and having a moderately long torso, these are one of the few bib shorts in a L that have long enough straps I can wear them and not end up with stiff shoulders, neck and upper back from the straps digging in, especially on long and/or vigorous rides.
These are definitely pricey, but well worth the sale price cost. Hoping they last for many years of use and I bought a few at a time to have plenty to rotate.
