I really like these tights. They're perfect for fall and spring conditions in Oregon...maybe even a mild winter day. They say thermal but I would describe them as super cold weather tights, as in the 30s. I haven't tried them yet on a really cold day but they don't feel thermal enough for freezing cold temps (then again, I'm kind of a wimp when it comes to getting cold).
I've worn them in wet conditions45 degrees and they were perfect.
I also like the fact that the chamois isn't the size of a pole vault pit. What is it with the size of chamois in women's shorts and tights? I tried on several other brands (Gore, Sugoi, Castelli) before these and could not believe how huge and thick the chamois was. Gah! Um, no thank you, I don't care to ride in a huggie diaper.
I'm 5'4 110lbs. Waist 28, Hips 35, Inseam 29.5 and the size small fits me perfectly.
