My third PI Quest bib short and for the price, they remain hard to beat. The fit is excellent--PI tends to be generous and I sized down from other brands I wear based on the online size chart and it was spot on. The chamois works for the rides I tend to do (up to 30 miles at a go) and so far, I can't complain. The thigh grip has been good so far, keeping the shorts where they need to be, the straps are comfortable and the panel above the waist gives good support to the core and lower back. I picked the Twilight and to be honest, the photo shows up as darker than it actually is--it's closer to a teal than dark blue in reality. But to my eyes, that was an upgrade--a nice change from my collection of basic black bibs.
I own the original unlimited and the 2nd generation unlimited, both in Medium for my XC MTB and
road bike. The 2nd generation felt tighter than the original Unlimited so I ordered a large in the endurance. Between a medium and a large I don't see a big difference, they both work. What I do know is during the first few miles it seemed like Castelli forgot the chamois but now it's my favorite part of the bibs. FWIW, I typically use Giordana FRC-Pro and Vero Pro bibs and so far I prefer the Castelli Unlimited Endurance.
Good jersey for those changeable Spring and Autumn days. It's a comfortable cut and easy to layer as called for. With a thermal baselayer and and a good jacket, it works for cooler days (7-12C/45-52F) while dropping layers will allow you to use comfortably on warmer (15-21C/60-70F) days.
Got the red (PI calls it ketchup) and it fit well. The cut is relatively generous--I sized down from my usual size with other brands but the recommended size was pretty accurate. I like the fact there is no shoulder seam--makes the jersey sleeker. Pockets are good: they easily fit my phone, keys, rain jacket and the necessary snack for long rides.
