Buyer beware! I bought a pair of these for my wife. These are NOT thermal. Specialized says they are fleece lined but I would beg to differ 100%. Poor advertising on Specialized. If you’re looking for normal bib knickers for cool weather, these may be the way to go. However, these do not hold up well in cold temps.

Although these are super nice, comfy & functional they are NOT thermal. Rather simply amazing lightweight knickers.

I initially thought I was simply sent the wrong product as the the tag on the knickers doesn't say thermal and they are extremely thin and in no way seem to be for cold weather use. Upon researching more the product numbers match and the ones I received are supposed to be the "thermal" ones. I wish I had seen the other reviews before ordering these because they aren't going to cut it for Colorado winter riding which is really disappointing.

They are not thermal. I put them on and walked out when it was only 47 degrees, and immediately could feel the cold on my legs. The quality of the material may be good but it is thin. Not anything like my RBX specialized biking shorts that I love. These would have to be worn under or over something warmer. I do like the chamois design and have found RBX design suits my needs in that area. So I’ll take these as a loss and try them in the spring or early fall months. Still would like their long pants but with thicker material.

I purchased hoping they could be used as a warm thermal layer. However, they were very thin. The waist is lower than I prefer as well. Not what I expected but I will be able to use them for a different purpose.

I was really excited to get these in time for the colder weather. Unfortunately, when I received these they were not thermal and you can actually see through them. I checked the item number and it matches the one on the web site. I am keeping them anyway for warmer weather as they are very comfortable but now I am left without the thermal knickers I was hoping for.
