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.
My size medium Trenta fits my head (58cm circumference) almost perfectly--not tight, but not so loose I need to ratchet the retention system fully to keep it in place. Ive worn the Trenta on several rides in temps ranging from low 80s to mid 90s, and ventilation is fine. The helmet weighs 297g on my scale, which is on par with other premium MIPS or MIPS-like helmets I own...A couple of minor issues prevent this from being a great helmet: 1) The front retention straps are anchored relatively far back, to the point where they overlap my earlobes. I was able to adjust them a so they barely clear my ears, but I've never had to do this with any other helmet and it took a lot of fiddling around to fix this. 2) The back of the helmet interferes with some of my sunglass arms--POCs bump up against the helmet, but my S-Phyre glasses fit with no contact.
These are very light and bright gloves with a lot of elasticity. But the seams have broken along a few parts that move a lot, especially near the thumb. I was able to repair them once, but then some different seams fell apart.
The mitten feature is interesting but not practical as the fabric is too thin to really act as protection against cold even with two layers.
