Bib tights work well in my N. California climate for most winter riding (even colder fallspring mornings), but I wanted something a bit warmer than my unlined Pearl Izumi knickers for truly cold winter days. The addition of fleece make these much warmer, however, the fit on the P.R.O.'s is a bit tighter and with a thin layer of fleece, they fit much tighter than my non-P.R.O.'s in the same size. I cannot go up in size because they become too long. They suit their purpose and they look great, but just understand that the P.R.O. line is snug.
I really enjoy wearing these bibs when the weather is still ride-able but not so cold your face freezes off. The fleece inside makes them warm inside like your flannel pajamas!
First ride wasnt sure about them but Ive used these numerous times now and really like them. Im 60 and 185 and the size medium worked well. Worn them up to 55-60 degrees and as low as 40s and worked perfectly.
Fit is right on. I'm 170 5'11 and the med was a great fit. Comfortable on road rides into mid 40's and mtb and gravel rides into the upper 30's. They don't ride up and the material doesn't bunch behind the knee. The chamois is nice. Not as nice as ASSOS S7 but comfortable on long rides
These bibs really do the trick in keeping the cold off when the temps dip below 50. I've used them predominately in 40-55 degree weather and have absolutely loved them. They fit well and the chamois is comfortable enough for long rides without really noticing them - which is great.
I bought a size small for winter riding. It felt a little tight in the beginning but after break-in or three four-hour rides and three washings the fit is perfect. The compression on the legs and the strap tension are just right . The moisture transfer or wicking feature works. After a hard long ride I dont feel wet in the chamois area. It is very comfortable. Nice seamless straps and overall clean cut. Unlike my other bib-shorts I want to change right away upon arriving home. With these bib-knickers it felt like I want to wear them all day. I also bought the Castelli Sorpasso2 bib knicker (medium). The fit of the Pear Izumi (small) is better for me. My measurements chest 34 in, waist 31.5 in, hips 33.5 in, mid-thighs 18 in. I hope this helps in deciding your size.
I use these 34 length with short socks down to 40F degrees and with tall socks down to about 25F. Below that I put on a top-layer of tights. Keeps me outdoors and off the rollerstrainers.
This must be Pearl Izumis lower-end chamois, because it is bulky and uncomfortable compared to every other pair of PI bibs I own. The bibs themselves are nicely made and do keep my knees and thighs warm on chilly or damp days.
I am a big fan of knickers. Rarely if ever do I wear a full tight, as the shins are not that sensitive to cold. And if it's that cold that I am worrying about cold shins, well, I'm headed to the gym instead of outdoors! Having said that, I am also a big fan of PI, particularly their various bottoms. These particular knicks have modest loft, a great chamois, and the best leg grippers I have experienced yet. Hopefully they will also prove durable, as have most of my other PI pieces.
These tights are great for the typical winter ride weather here in NorCal, high 40's to low 60's.
Super comfortable and warm. I liked them so much I bought a second pair! True to size and easy to keep clean
