The material feels soft, it's very stretchy and won't inhibit pedaling performance. I'm 5'11" 150 lbs and the Large is too big it's actually swimming around my calves it won't do. All the Castelli bibs or tights in size Large have fit me perfectly just like Pearl Izumi size Medium, but on this particular item I need a Medium. Since there aren't any available this will be returned. Bummer because I would really love this tight it feels like it would be perfect for temps when a bib short isn't quite enough and the Sorpasso is slightly too much. It feels lighter than its scale weight by a mile very impressive fabric, cut, thickness, etc...
This tight serves me well in mid-40s and warmer. Great pad (similar to their summer bibs). Works very well for most cooler temps (you will need something more robust for 30s). I love the "radio" pocket feature on the back; great for storing my iPhone. Highly recommended.
I bought these in the middle of summer when they were on sale so I have't been able to wear them yet but I'm sure they will be excellent. I own plenty of Castelli gear and haven't been disappointed yet.
