William M.wrote a review of Shimano S-Phyre Bib Long Tight - Men's on November 5, 2019
Familiarity: I've used it several times
I ordered these with high hopes that they'd be my go-to when the weather is cold and/or messy, but, after wearing them a few times, I'm left wondering what the goal of this product really is and why they selected the materials they used.
The good: Nice chamois. No complaints there. As a pair of tights, they do a pretty solid job, but I'm going to be less likely to wear them much below 40 or if it's wet, which is what you might think they are best for by looks, design, and materials. The knee and lower quad area does have some wind block, but, in my opinion, it's needed elsewhere.
The bad: I'm guessing that the neoprene lower leg would do a good job with heavier water, but the rest of the tights don't seem to match up with that goal. In addition, every time I've worn these, my shins are soaked in sweat because the neoprene doesn't breathe at all. I'd be fine putting up with some shin sweat if the rest of the bib seemed to fit the premise of the lower legs, but that's where there is the disjointed design process seems to come in. There's no butt protection from the spray that you'll surely encounter while needing heavy neoprene on your shins. Absolutely nothing. There's no additional wind protection in the front of the groin either. If I'm going out in such nasty conditions that my shins need 2-3mm thick neoprene, you'd better believe I'm going to want something up front and attempting to keep my butt dry. I took these out in low 30F temps and came home with hot and sweaty shins and a numb penis. I'll take the opposite 10 times out of 10.
I think that many cyclists have agreed that their shins will survive on their own just fine. It's the last piece of skin to get covered up when the temps drop (knee warmers, knickers), so why are they getting the heaviest coverage of any part on these tights while the whole groin area gets completely ignored? The only scenario I can see where these work great is wet (not raining) but fully fendered bike and no colder than 40F degrees.
